Advanced lung cancer inflammation index is associated with mortality in critically ill 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
backgroundNutritional and inflammatory status are closely associated with outcomes in Acute Kidney Injury (AKI). This study investigated the association between the Advanced Lung cancer Inflammation index (ALI), a composite nutrition-inflammation marker, and short-term mortality in critically ill patients with AKI.
methodsWe conducted a retrospective cohort study using the MIMIC-IV database. A total of 1887 adult ICU patients with AKI were included. ALI was calculated as body mass index × serum albumin / neutrophil-to-lymphocyte ratio. The primary outcome was all-cause in-hospital mortality, and the secondary outcome was 90-day mortality. Kaplan-Meier curves, Cox proportional hazards models, restricted cubic spline analysis, and subgroup analyses were performed.
resultsThe median age was 68.0-years, and 62.4% of patients were male. In-hospital and 90-day mortality rates were 25.2% and 33.9%, respectively. Patients in the lowest ALI tertile had significantly higher cumulative mortality than those with higher ALI. After full adjustment, higher ln(ALI) was independently associated with lower in-hospital mortality (HR = 0.86; 95% CI 0.79-0.93; p < 0.001) and lower 90-day mortality (HR = 0.81; 95% CI 0.75-0.87; p < 0.001). Restricted cubic spline analysis showed an approximately linear inverse association between ALI and in-hospital mortality.
conclusionsLower ALI was associated with higher short-term mortality in critically ill patients with AKI, but this association was substantially attenuated after full adjustment and was largely confined to non-septic AKI. This retrospective single-center analysis supports an association but does not establish clinical utility; prospective multicenter external validation is needed before ALI can be recommended for risk stratification.
