Association Between Diurnal Temperature Range and Risk of Cardiomyopathy-Induced Hospitalisation in Henan, China: A Time-Series Study.

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: The effect of the diurnal temperature range (DTR) on human health in diverse geographic areas and the potential confounding factors are not fully understood. Additionally, while a robust association has been reported between temperature and cardiomyopathy (CM), evidence of the impact of DTR is relatively limited. Here, we determined whether an association exists between DTR and CM hospitalisations in vulnerable populations. Methods: CM admission data (2016-2021) were collected from seven tertiary hospitals in Henan.We used a GAM combined with a distributed lag non-linear model (DLNM) to investigate the delayed effects of DTR on daily hospitalisations for CM.Stratified analysis was performed in subgroups according to sex, age, and season. Attributable fractions (AF) and attributable numbers (AN) were employed to illustrate the disease burden and investigate the association between temperature and DTR. Results: Overall, 5,757 CM cases were identified. DTR and CM admissions exhibited a non-linear correlation. High DTR (P95: 15.5 °C) and low DTR (P05: 3 °C) increased CM admission risk, with low DTR having a stronger effect. Males and warm seasons were significantly more susceptible to DTR, and low DTR affected youth and adults more than older adults. AF and AN of low DTR on CM admissions were 51% and 2,936, respectively. Conclusion: Our results revealed a significant association between DTR and CM hospitalisations, providing valuable insights for the development targeted prevention and control measures.
