Elevated atherogenic index of plasma is associated with severe acute kidney injury in critically ill patients with cardiovascular disease - a MIMIC-IV analysis with external validation in the eICU-CRD database.

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
The atherogenic index of plasma (AIP) is a lipid-based marker of cardiovascular risk, yet its prognostic value for severe acute kidney injury (AKI) in critically ill patients with cardiovascular disease (CVD) remains uncertain. This retrospective study analyzed 5,872 patients from the Medical Information Mart for Intensive Care IV (MIMIC-IV) database, with external validation in the eICU Collaborative Research Database (eICU-CRD). The primary outcome was stage 3 AKI, and secondary outcomes included renal replacement therapy (RRT) and length of stay. Stage 3 AKI was observed in 20.7% of patients, with the incidence increasing across AIP quartiles (Q1-Q4: 15.9-26.8%), and 5.3% of patients requiring RRT (Q1-Q4: 2.6-10.9%). High AIP was associated with stage 3 AKI (adjusted OR = 1.35; 95% CI: 1.11-1.64), RRT (OR = 1.95; 95% CI: 1.33-2.87), longer hospital LOS (β = 3.58;
