Heat stress exposure and incidence of chronic kidney disease.
Article in iScience, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Long-term repeated heat stress may contribute to chronic kidney disease (CKD). In this ecological study, we examined country-level associations between heat stress exposure and CKD incidence using data from 174 countries during 1990-2021. Annual numbers of days with four heat stress levels (moderate, strong, very strong, and extreme) were assessed using the Universal Thermal Climate Index. A weighted heat stress score was generated from these four levels. Linear mixed-effects models were used to evaluate the associations. Each additional day of moderate, strong, very strong, and extreme heat stress was associated with increases of 0.088 (95% confidence interval [CI]: 0.035-0.140), 0.095 (0.047-0.142), 0.097 (0.036-0.159), and 0.782 (0.643-0.921) incident cases per 100,000 population, respectively. The weighted heat stress score was consistently associated with an increased incidence of CKD. These findings may imply that attention should be paid to the potential disease burden of heat-related CKD.
