1 · What the graph read from it

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.

2 · The registry

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

backgroundUrbanization and climate change have increased temperature extremes contributing to chronic kidney disease (CKD) risks. Using 1990-2021 Global Burden of Disease (GBD) data, we analyzed trends and disparities in CKD burden attributable to non-optimal temperatures across regions, genders, and time.

methodsData on CKD mortality and disability-adjusted life years (DALYs) were extracted from GBD 2021. Trends were evaluated using estimated annual percentage change (EAPC). Age-period-cohort (APC) modeling quantified age, period, and cohort effects. Age-standardized mortality rate (ASMR) and age-standardized DALY rate (ASDR) expressed burden per 100,000 population. Concentration indices assessed socioeconomic health inequalities, while demographic decomposition disentangled contributions of population aging, growth, and epidemiological changes.

resultsLow-temperature-attributable CKD dominated globally in 2021 (ASMR: 0.99 [0.84-1.12]; ASDR: 20.27 [17.11-23.53]), exceeding high-temperature-attributable burden (ASMR: 0.21 [- 0.01 to 0.49]; ASDR: 5.74 [0.13-12.99]). Over three decades, high-temperature burden increased markedly, while low-temperature effects remained persistently elevated. Males and older adults showed disproportionate vulnerability. Low-SDI regions exhibited heightened sensitivity to heat, whereas high-SDI regions were more affected by cold. Decomposition revealed epidemiological changes as key drivers for heat-related burden versus population aging for cold-related burden. Health inequalities intensified for heat-related outcomes but declined for cold-related impacts.

conclusionsNon-optimal temperatures impose differential CKD burdens globally, shaped by socioeconomic disparities and demographic shifts. Targeted interventions addressing gender-, age-, and SDI-stratified vulnerabilities, coupled with climate-resilient health policies, are urgently needed to mitigate temperature-driven kidney disease risks.
