| Title: | Methods for Analysing 'EQ-5D' Data and Calculating 'EQ-5D' Index Scores |
|---|---|
| Description: | EQ-5D is a popular health related quality of life instrument used in the clinical and economic evaluation of health care. Developed by the EuroQol group <https://euroqol.org/>, the instrument consists of two components: health state description and evaluation. For the description component a subject self-rates their health in terms of five dimensions; mobility, self-care, usual activities, pain/discomfort, and anxiety/depression using either a three-level (EQ-5D-3L, <https://euroqol.org/information-and-support/euroqol-instruments/eq-5d-3l/>) or a five-level (EQ-5D-5L, <https://euroqol.org/information-and-support/euroqol-instruments/eq-5d-5l/>) scale. Frequently the scores on these five dimensions are converted to a single utility index using country specific value sets, which can be used in the clinical and economic evaluation of health care as well as in population health surveys. The eq5d package provides methods to calculate index scores from a subject's dimension scores. 33 TTO and 11 VAS EQ-5D-3L value sets including those for countries in Szende et al (2007) <doi:10.1007/1-4020-5511-0> and Szende et al (2014) <doi:10.1007/978-94-007-7596-1>, 49 EQ-5D-5L EQ-VT value sets, the EQ-5D-5L crosswalk value sets developed by van Hout et al. (2012) <doi:10.1016/j.jval.2012.02.008>, the crosswalk value sets for Bermuda, Jordan and Russia and the van Hout (2021) reverse crosswalk value sets. 13 EQ-5D-Y-3L value sets are also included as are the NICE 'DSU' age-sex based EQ-5D-3L to EQ-5D-5L and EQ-5D-5L to EQ-5D-3L mappings. Methods are also included for the analysis of EQ-5D profiles, including those from the book "Methods for Analyzing and Reporting EQ-5D data" by Devlin et al. (2020) <doi:10.1007/978-3-030-47622-9>. Additionally a shiny web tool is included to enable the calculation, visualisation and automated statistical analysis of EQ-5D data via a web browser using EQ-5D dimension scores stored in CSV or Excel files. |

Computes the Health Profile Grid (HPG) for two sets of EQ-5D health states. The HPG displays pre- and post-intervention utility ranks and the associated PCHC category for each subject.
Two input interfaces are supported:
1. Wide-form input (default method)
hpg(pre, post)
where pre and post are EQ-5D health states represented either as:
5-digit EQ-5D profiles (character or numeric), or
data.frames with dimension columns MO, SC, UA,
PD, AD
2. Long-form input (formula method)
hpg(formula, data)
where the formula has left-hand side forms:
a single 5-digit EQ-5D profile column
dimension columns, e.g. MO + SC + UA + PD + AD
cbind(MO,SC,UA,PD,AD)
and right-hand side of the form time | id, where:
time is the visit variable
id is the subject identifier
For formula methods the time variable must contain exactly two observable
levels unless the user specifies pre.level and post.level.
When not supplied, the ordering of pre- and post-measurements is determined
automatically as follows:
factor time variables use the factor level order
character or numeric time variables use the order of appearance

Computes the Paretian Classification of Health Change (PCHC) for EQ‑5D data. PCHC classifies change between two EQ‑5D health states into:
Improve
Worsen
No change
Mixed change
No problems (optional)
The method applied depends on the class of the first argument:
pchc.default() for wide‑form data with explicit pre/post states
pchc.formula() for long‑form data using a formula interface
Computes the Paretian Classification of Health Change from wide-form EQ-5D data where pre- and post-intervention states are supplied as separate objects.
Computes the Paretian Classification of Health Change from long-form EQ-5D data using a formula interface.

A long‑form data.frame used with the formula interface. |
formula |
A formula specifying EQ‑5D variables on the left‑hand side and a time variable (and optionally an ID variable) on the right‑hand side. This argument is used only in the formula interface. |
When summary = FALSE, the function returns individual‑level PCHC
classifications, one per subject. When summary = TRUE, it returns
a tabular summary reporting counts and percentages by PCHC category,
suitable for reporting.
The totals argument applies only when summary = TRUE; it is
ignored otherwise.
Missing or invalid EQ‑5D values are handled consistently across all methods
via the ignore.invalid argument.
For formula methods the time variable must contain exactly two observable
levels unless the user specifies pre.level and post.level.
When not supplied, the ordering of pre‑ and post‑measurements is determined
automatically as follows:
factor time variables use the factor level order
character or numeric time variables use the order of appearance
When summary = FALSE and by.dimension = FALSE, a character
vector of individual-level PCHC classifications.
When summary = TRUE and by.dimension = FALSE, a data.frame
summarising PCHC categories with counts and percentages.
When by.dimension = TRUE, a named list is returned with one element
per EQ-5D dimension. Each element is a character vector (when
summary = FALSE) or a data.frame (when summary = TRUE).

representation of the EQ-5D descriptive system.
The descriptive system summarises the distribution of response levels within each EQ-5D dimension. Bars are shown side-by-side to facilitate comparison across response levels. When grouped data are supplied, the plot uses faceting to aid comparison across groups while avoiding overplotting and excessive use of colour.

This function is a pure visualisation layer and expects the output of
hpg. No analytical computation is performed.
The input to plot_hpg() is the result of hpg(), which may be
generated using paired pre- and post-measurement data (for example as
vectors or data frames), or via an alternative formula interface supported
by hpg().
Transition classes follow the terminology and ordering used in the reference book: Improve, Mixed change, No change, Worsen, and No problems. Only transition classes present in the plotted data are shown in the legend.
The Health Profile Grid is intended for paired data and illustrates how individuals move between health states over time. Points on the diagonal indicate no change, while points above the diagonal represent improvement and points below the diagonal represent deterioration.

The input data must be a pre-computed cumulative distribution,
typically returned by eq5dcf or make_hsdc_by_group.
This function performs no analytical computation; it only visualises
the supplied data.
Axes are displayed as cumulative percentages (0–100%). A 45-degree reference line indicates a perfectly even distribution of health states.
Curves that lie close to the diagonal indicate an even distribution of health profiles. Curves that lie further below the diagonal indicate increasing concentration of observations on a small number of health states.

Computes the Probability of Superiority (PS) for each EQ‑5D dimension based on the Paretian Classification of Health Change (PCHC).
PS quantifies whether post‑intervention EQ‑5D states tend to be superior to pre‑intervention states:
Interpretation:
PS < 0.5: deterioration dominates
PS = 0.5: improvement and deterioration balanced
PS > 0.5: improvement dominates
Two interfaces are supported:
1. Wide‑form input (default)
ps(pre, post) where pre and post are EQ‑5D states in
5‑digit form or data frames containing EQ‑5D dimension columns.
2. Long‑form + formula interface
ps(formula, data) mirroring the interface of pchc().
For formula methods, the time variable must contain exactly two observable
levels unless the user specifies pre.level and post.level.
When not supplied, the ordering of pre‑ and post‑measurements is determined
automatically as follows:
factor time variables use the factor level order
character or numeric time variables use the order of appearance
Computes the Probability of Superiority from wide‑form EQ‑5D data where pre‑ and post‑intervention states are supplied as separate objects.
Computes the Probability of Superiority from long‑form EQ‑5D data using a formula interface.

Formats EQ-5D descriptive system summaries into publication-ready tables.
This function is the reporting-layer companion to
descriptive_data, and mirrors the tabular presentation
recommended in the EQ-5D reference literature and implemented by the
Stata eq5dds command.
Tables contain either percentages or counts, depending on the metric
supplied to descriptive_data. No analytical computation
is performed by this function.

This function operates on the output of descriptive_data,
which returns tidy descriptive-system summaries with one row per
Dimension–Level–Metric combination. Values are reshaped into wide
tables for reporting.
Counts and percentages are generated via separate calls to
descriptive_data, consistent with the presentation in
the EQ-5D reference literature.
When descriptive data are grouped, table_descriptive() returns
a named list of tables, one per group, consistent with the behaviour
of eq5dds when used with subgroup reporting.
If descriptive data are ungrouped, a data.frame. If grouped, a named list of data.frames, one per group.
