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
Objective: This study investigated the relationship between indoor temperature, humidity, and sleep quality in private residential care homes for persons with disabilities (PRCHDs) in Hong Kong, a vulnerable and under-researched population. Methods: A 6 month pilot study (August 2024-February 2025) was conducted in three PRCHDs. Smart sensors monitored indoor temperature and relative humidity in dining areas and bedrooms. Thirty residents with disabilities residing in PRCHDs completed four surveys assessing sleep quality using the Pittsburgh Sleep Quality Index (PSQI). Time-series analysis compared indoor conditions with outdoor data, while statistical models analyzed associations between PSQI scores and environmental factors. Results: Many participants residing in experienced poor sleep quality (PSQI > 5), especially in summer (30-73%). Indoor temperatures in PRCHDs often exceeded outdoor levels, particularly during warmer months. Significant associations were observed between sleep quality and indoor temperature, relative humidity, sleeping periods, and self-perceived humidity ( Conclusion: Findings highlight the need to improve environmental conditions in PRCHDs, particularly during summer. Recommendations include improving ventilation, increasing air conditioning use, and promoting outdoor activities to enhance sleep quality and overall well-being.
