Seasonal variations in acute kidney injury incidence and outcomes: a multicenter prospective observational study highlighting socioeconomic disparities.
Observational study in Renal failure, 2025. 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
backgroundKuwait experiences cool winters and hot summers. We evaluated the impact of ambient temperature in these two seasons on acute kidney injury (AKI) incidence and outcomes, and assessed difference between Kuwaitis and non-Kuwaitis.
methodClinical and 30-day outcome data from AKI patients who were admitted to seven public hospitals during winter and summer of 2021 were prospectively collected.
resultsTotal number of AKI cases during both seasons was 1,493. Incidence was same in both seasons (50.0% each). Kuwaitis accounted for 56.7% of cases. Most AKI cases for Kuwaitis occurred in winter (52.4%), while most for non-Kuwaitis occurred in summer (53.2%). AKI patients in winter were significantly older (64.8 vs. 62.0 years,
conclusionNo seasonal variations in AKI incidence, dialysis need, or mortality rate. In winter, AKI occurred more in older with more comorbidities among Kuwaitis but better socioeconomically, while in summer, AKI occurred more in younger, healthier non-Kuwaitis but socioeconomically disadvantaged.
