Health-related quality of life in racial and ethnic minority adults with type 2 diabetes: validity and responsiveness of the EQ-5D-3L.
Trial report in Quality of life research : an international journal of quality of life aspects of treatment, care and rehabilitation, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02990299 (mHealth for Diabetes Adherence Support), which is not on this map.

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.

Abstract
purposeHealth-related quality of life (HRQL) assessment provides insights into the lived experiences of diverse populations. This study evaluated the convergent validity and responsiveness of the EQ-5D-3L in racial/ethnic minority populations with type 2 diabetes and elevated hemoglobin A1c (HbA1c).
methodsSecondary data from a clinical trial of a diabetes adherence support intervention for African-American and Latinx patients with type 2 diabetes (NCT02990299) were analyzed. Clinical (HbA1c, systolic blood pressure [SBP], body mass index [BMI]), psychological (brief 4-item diabetes distress scale [DDS4] for diabetes-related distress, 9-item patient health questionnaire [PHQ-9] for depressive symptoms), and HRQL (EQ-5D-3L) data were collected at baseline and every 6 months for 2 years. Convergent validity was assessed by examining the strength of associations between clinical/psychological measures and EQ-5D scores. A responder analysis using generalized estimating equation models was used to evaluate the EQ-5D's sensitivity to changes in clinical/psychological factors over time.
resultsAmong 221 individuals analyzed, HbA1c and SBP levels did not differ across those reporting varying levels of problems in any EQ-5D dimension. Individuals with higher BMI were more likely to report problems with mobility, usual activities, pain/discomfort, and anxiety/depression. DDS4 scores were moderately correlated with EQ-5D anxiety/depression dimension and index score, while PHQ-9 scores were strongly correlated with both. EQ-5D index score was insensitive to improvements in clinical measures but sensitive to improvements in psychological measures over time.
conclusionThe EQ-5D-3L captured variations in BMI and psychological measures but not in HbA1c and SBP. This study provides HRQL estimates that can be compared with other populations or studies.
