Association between stress hyperglycemia and acute kidney injury requiring dialysis in critically ill patients with sepsis: a hospital-based cohort study.
Article in Jornal brasileiro de nefrologia. 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
introductionStress hyperglycemia in patients with sepsis has not been consistently associated with an increased risk of acute kidney injury (AKI).
objectiveTo evaluate the effect of blood glucose levels on the occurrence of AKI requiring dialysis in critically ill patients with sepsis.
methodsRetrospective cohort study of patients with sepsis admitted to the ICU of a private hospital between December 2017 and August 2021. Clinical, laboratory, and severity variables were collected. Mean blood glucose levels in the first week of ICU stay (primary exposure variable) were stratified into tertiles. The effect of blood glucose on the occurrence of dialysis-requiring AKI was assessed using multivariate logistic regression.
resultsOf the 1,317 patients evaluated, 86.6% had clinical conditions as the underlying cause of sepsis. AKI requiring hemodialysis occurred in 12.2% of the sample. Patients with mean blood glucose levels above the third tertile (≥160 mg/dl), compared to those with mean blood glucose levels below the first two tertiles (<160 mg/dl), had a higher prevalence of diabetes (69.1% vs. 7.1%; p < 0.001). Patients with mean blood glucose levels ≥160 mg/dl had a 62% higher odds of developing AKI requiring dialysis compared to those with mean blood glucose levels < 160 mg/dl (crude OR = 1.62; 95% CI 1.16-2.26; p = 0.005). After adjustment for other variables, mean blood glucose levels ≥180 mg/dl did not increase the likelihood of AKI (OR = 1.27; 95% CI 0.76-2.12; p = 0.359).
conclusionIn this patient group, sepsis and mean blood glucose levels ≥160 mg/dl were not independently associated with the occurrence of dialysis-requiring AKI.
