Association of Exposure to Humidex with Schizophrenia Admissions in Qingdao, China: A Time-Series Study.
Article in Neuropsychiatric disease and treatment, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Purpose: This study aimed to quantify the effects of humidex (a composite index of temperature and relative humidity) on schizophrenia admissions. Methods: The exposure-lag-response relationship between humidex and schizophrenia admissions was explored via a distributed lag nonlinear model (DLNM). The modification effects of sex and age were also investigated. We further calculated the attributable fraction (AF) and number (AN) due to humidex. Results: During the study period, the median humidex in Qingdao was 15.22, and the low humidex (-7, 2.5th percentile) and high humidex (40, 97.5th percentile) were -7 and 40, respectively. The significant adverse effects of low humidex on schizophrenia admissions persisted from lag 2 [Relative risk (RR)=1.060, 95% CI (confidence interval): 1.006-1.117] to lag 5 (1.063, 1.008-1.122) and reached its maximum at lag 4 (1.078, 1.008-1.152). Females and young individuals are susceptible to low humidex. In addition, the AFs and ANs of schizophrenia admissions due to low humidex were 7.2% and 407, respectively. Conclusion: Schizophrenia admission was associated with only low humidex. Humidex may serve as an early warning indicator of schizophrenia.
