Crosswalks EQ-5D-5L responses to EQ-5D-3L utilities using NICE's mapping.

The EQ-5D is a widely-used standarized instrument for measuring Health Related Quality Of Life (HRQOL),
developed by the EuroQol group <https://euroqol.org/>. It assesses five dimensions; mobility, self-care,
usual activities, pain/discomfort, and anxiety/depression, using either a three-level (EQ-5D-3L) or five-level (EQ-5D-5L) scale.
Scores from these dimensions are commonly converted into a single utility index using country-specific value sets,
which are critical in clinical and economic evaluations of healthcare and in population health surveys.
The eq5dsuite package enables users to calculate utility index values for the EQ-5D instruments,
including crosswalk utilities using the original crosswalk developed by van Hout et al. (2012) <doi:10.1016/j.jval.2012.02.008>
(mapping EQ-5D-5L responses to EQ-5D-3L index values), or the recently developed reverse crosswalk
by van Hout et al. (2021) <doi:10.1016/j.jval.2021.03.009> (mapping EQ-5D-3L responses
to EQ-5D-5L index values). Users are allowed to add and/or remove user-defined value sets.
Additionally, the package provides tools to analyze EQ-5D data according to the recommended
guidelines outlined in "Methods for Analyzing and Reporting EQ-5D data" by Devlin et al. (2020) <doi:10.1007/978-3-030-47622-9>.

eqxw_UK function

<dl><dt>x</dt>
<dd>A vector of 5-digit EQ-5D-5L states (domain scores) or a summary score.</dd>
<dt>age</dt>
<dd>A numeric vector or column name (if `x` is a data frame). Can be either:
(1) a numeric age between 18 and 100, which will be automatically grouped into NICE-defined age bands (18-35, 35-45, 45-55, 55-65, +65), or
(2) a factor/character/numeric vector already representing the NICE age bands with values 1-5 indicating age bands (18-35, 35-45, 45-55, 55-65, +65).</dd>
<dt>male</dt>
<dd>A numeric vector (1=male, 0=female) or column name indicating gender.</dd>
<dt>dim.names</dt>
<dd>A vector of dimension names for EQ-5D states (default: c("mo", "sc", "ua", "pd", "ad")).</dd>
<dt>bwidth</dt>
<dd>Numeric. Bandwidth for kernel smoothing when using summary scores.</dd></dl>
