Relationship between remnant cholesterol and acute kidney injury in ICU patients: insights derived from MIMIC IV.

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
backgroundRemnant cholesterol (RC) reflects the cholesterol content of triglyceride-rich lipoproteins, but its association with acute kidney injury (AKI) among patients in the intensive care unit (ICU) has not been adequately investigated.
methodsWe analyzed data from the Medical Information Mart for Intensive Care IV (MIMIC-IV) database. The primary outcome was incident AKI. Cox proportional hazards regression, restricted cubic spline analysis, and subgroup analyses were used to evaluate the association between RC and AKI risk in ICU patients. Kaplan-Meier curves were used to compare time to AKI across RC quartiles.
resultsA total of 5535 patients were included, of whom 55.66% developed AKI during their ICU stay. In the fully adjusted Cox model, the hazard ratios (HRs) for AKI in the third and fourth RC quartiles were 1.13 (95% confidence interval [CI], 1.02-1.25) and 1.19 (95% CI, 1.08-1.32), respectively, compared with the first quartile. Restricted cubic spline analysis showed no evidence of a nonlinear association between RC and AKI risk (p for nonlinearity = 0.146). Kaplan-Meier analysis further showed that patients in the highest RC quartile had the greatest cumulative incidence of AKI (log-rank p < 0.001).
conclusionElevated RC was independently associated with an increased risk of AKI during the ICU stay. Prospective and interventional studies are needed to clarify causality and determine whether RC measurement or RC-targeted management has clinical value.
