Risk analysis and mediation analysis of stress hyperglycemia ratio and all-cause mortality in patients with acute kidney injury.

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
backgroundStress hyperglycemia ratio (SHR) has been associated with increased mortality from various cerebrovascular events and a higher incidence of acute kidney injury (AKI) in certain patient populations. However, the relationship between SHR and the mortality risk in patients with AKI has not been fully elucidated. Our study sought to comprehensively investigate the association and potential mediating effects between SHR and 28-day and 90-day mortality in patients with AKI.
methods3703 patients with AKI were included in this study. Feature importance variables were screened by a random forest algorithm, and the independent association of SHR with mortality risk was determined by Kaplan ‒ Meier survival analysis with Cox regression analysis. Restricted cubic spline (RCS) was conducted to assess the non-linear relationship between SHR and mortality risk. Mediation analysis was deployed to investigate the indirect effect of SHR on respiratory failure (RF) -mediated mortality risk.
resultsAmong the patients with AKI included in this study, the 28-day mortality was 13.6% and the 90-day mortality was 18.7%. Fully adjusted Cox regression demonstrated that SHR was an independent risk factor for 28-day mortality (HR, 1.77 [95% CI 1.38-2.27], P < 0.001) and 90-day mortality (HR, 1.69 [95% CI 1.36-2.11], P < 0.001) in patients with AKI. RCS analysis revealed a linear relationship between SHR and outcome events. Additionally, the effect of SHR on 28-day and 90-day mortality risk were mediated by an increased RF risk in 6.62% and 6.54%, respectively.
conclusionHigh SHR is an independent risk factor for 28-day and 90-day mortality in patients with AKI, and its effect is partly mediated by an increased risk of RF.
