EQ-5D-5L population norms for Singapore: a household survey-based analysis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPopulation norms for the EQ-5D-5L are essential for health economic evaluations. However, existing norms for Singapore were established before the COVID-19 pandemic, whose prolonged health and societal impacts may have rendered them outdated. Updated post-pandemic benchmarks are therefore needed to inform cost-utility analyses and public health policy accurately. This study aimed to establish updated EQ-5D-5L population norms among Singapore residents aged ≥ 15 years and to examine variation in health-related quality of life (HRQoL) by sociodemographic characteristics.
methodsWe conducted a cross-sectional household survey between May and July 2024 among Singapore citizens and permanent residents, using a three-stage sampling strategy with demographic quotas. We assessed HRQoL using the EQ-5D-5L and EQ VAS. We derived index scores using the Singapore-specific value set. We generated descriptive statistics and used multivariable linear regression to identify independent associations between HRQoL and sociodemographic characteristics.
resultsThe analysis included 2,005 respondents. While 54.6% reported no problems ('11111'), pain/discomfort (30.7%) and anxiety/depression (27.1%) were the most prevalent issues. The mean EQ-5D-5L index score was 0.933 (SD 0.122), and the mean EQ VAS score was 82.3 (SD 13.3). Multivariable regression showed that older age was most strongly associated with lower HRQoL (p < 0.001). Higher socioeconomic status, measured by income and housing type, was independently associated with better HRQoL. Gender was not significantly associated with either outcome.
conclusionThis study provides updated, post-pandemic EQ-5D-5L population norms for Singapore. These norms offer an essential benchmark for interpreting EQ-5D-5L scores in cost-utility analyses and highlight priorities for addressing socioeconomic health inequalities.
