Impact of Sarcopenia on Renal Outcomes in Patients with Septic Acute Kidney Injury: A Retrospective Cohort Study.
Article in Yonsei medical journal, 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
purposeDespite the high prevalence of sarcopenia and the significant burden of septic acute kidney injury (AKI), the impact of sarcopenia on renal outcomes in patients with septic AKI has not been studied. Therefore, we aimed to evaluate the effect of sarcopenia on the renal prognosis of patients with septic AKI. MATERIALS AND
methodsThis retrospective study enrolled patients with septic AKI between July 2008 and March 2019. Sarcopenia was identified by measuring the total abdominal muscle area using abdominal CT. Patients were divided into sarcopenia and non-sarcopenia groups. The effect of sarcopenia on 90-day renal outcomes, including a >50% decrease in the estimated glomerular filtration rate, dialysis dependence, and requirement for continuous renal replacement therapy within 90 days, was analysed. Additionally, the effect of sarcopenia on 90-day mortality was assessed.
resultsOf the 608 enrolled patients with septic AKI, 273 (44.9%) were assigned to the sarcopenia group. At baseline, there were no significant differences in the severity score and distribution of AKI stages between the two groups. There was no significant between-group difference in the 90-day renal outcomes. Moreover, sarcopenia was not associated with 90-day renal outcomes across all AKI stages in stratified multivariable logistic analysis. In contrast, the 90-day mortality rates were significantly higher in the sarcopenia group than in the non-sarcopenia group (30.0% vs. 17.3%, respectively;
conclusionSarcopenia was significantly associated with an increased 90-day mortality rate; however, no significant association with 90-day renal progression was observed in patients with septic AKI.
