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
backgroundThe health impact of heatwaves is usually assessed using mortality, morbidity and healthcare service utilization. This study explored the feasibility of using subjective measures to capture and quantify the impact of heatwaves on the health and wellbeing of older adults.
methodsA cohort of residents aged ≥ 60 living in Fuzhou city, China, were surveyed four times: before summer in May, during heatwaves in June to July and August, and after summer in October, 2023. At all timepoints, the EQ-5D-5L, experimental EQ-HWB and self-designed questions assessing self-perceived effects of heatwaves were administered through one-on-one, face-to-face interviews. We examined the known-groups validity (using Cohen’s d effect sizes) and responsiveness (using standardized response mean [SRM]) of EQ-5D-5L, EQ-HWB and EQ-HWB-9 (including index values and level sum scores [LSSs]).
resultsThe responses of 579, 510, 473 and 508 residents were analysed in the four waves of survey, respectively. The ceiling effects for EQ-5D-5L items ranged from 58.2% (pain/discomfort) to 94.3% (self-care), while for EQ-HWB items, it ranged from 32.3% (accepted) to 94.0% (personal care). The EQ-5D-5L and EQ-HWB-9 index values, and EQ-HWB LSSs demonstrated discriminative ability in distinguishing between different groups based on the self-perceived impact of heatwaves, with most of the effect sizes being small (Cohen’s d: 0.04–0.31 for EQ-5D-5L; 0.16–0.34 for EQ-HWB-9; 0.28–0.45 for EQ-HWB). We found negligible responsiveness to improvements in self-perceived effects of heat (SRM: 0.07 to 0.18). Unexpectedly, improved health and wellbeing were observed during the first heatwave compared to pre-heatwave.
conclusionThe EQ-5D-5L, EQ-HWB and EQ-HWB-9 demonstrated satisfactory known-groups validity but limited responsiveness in measuring the health and wellbeing impact of heatwaves among Chinese older adults. Future research is recommended to further evaluate these measures as well as other outcomes measures for the purpose of quantifying the health and wellbeing impacts of heatwaves and other climate events.
