1 · What the graph read from it

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.

2 · The registry

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

objectiveWe aimed to synthesize the evidence on the construct validity and responsiveness of the EQ-5D and compare them with asthma-specific health-related quality-of-life scales, to guide further research and clinical applications in asthma.

methodsWe searched key databases from inception to 1 June, 2024 and used the COnsensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) method to appraise the evidence. The effect size estimates were aggregated using the inverse variance method to evaluate the relative efficiency of EQ-5D measures against the Asthma Quality of Life Questionnaire (AQLQ) and/or its corresponding preference-based index, Asthma Quality of Life-5 Dimensions (AQL-5D).

resultsThere were 493 tests (construct validity: 428; responsiveness: 65) drawn from 37 selected articles (validation: 7; clinical: 30). Overall, 78.4% and 76.9% of the a priori hypotheses for assessing construct validity (convergent validity: 56.4%; known groups: 88.5%) and responsiveness, respectively, were satisfied. The methodological quality was "very good" or "adequate" in 78.2% of construct validity tests and 92.3% of responsiveness tests. The pooled correlation coefficient between EQ-5D index and AQLQ total scores was 0.52 (95% confidence interval 0.43-0.59), and between EQ visual analog scale and AQLQ total scores was 0.53 (95% confidence interval 0.34-0.69). The Cohen's d ratios for the index, level sum scores, and visual analog scale compared to AQLQ were 0.56 (n = 27), 1.16 (n = 16), and 0.75 (n = 37). The EQ-5D index's Cohen's d ratio compared to AQL-5D was 0.49 (n = 5). The standardized response mean ratios for the index and visual analog scale compared to AQLQ were 0.26 (n = 11) and 0.63 (n = 9).

conclusionsThe EQ-5D demonstrated overall good validity and responsiveness in the adult asthma population. However, a comparison against disease-specific instruments suggested scope for improvement in its psychometric performance for this population.
