Association between the atherogenic index of plasma and acute kidney injury in sepsis patients.
Article in PloS one, 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
backgroundAlthough metabolic abnormalities are directly linked to acute kidney injury (AKI) in septic patients, the function of the atherogenic index of plasma (AIP) is yet unknown.
objectivesThis study examined the relationship between AIP and AKI risk in septic patients, providing insight into the role of lipid metabolism in renal injury.
methodsThis study investigated patients with sepsis using data from the eICU Collaborative Research Database (eICU-CRD). The AIP was calculated as the base-10 logarithm of the ratio of triglycerides to high-density lipoprotein cholesterol. We employed multivariate logistic regression to evaluate the association between AIP and AKI. Potential nonlinear relationships were assessed using restricted cubic spline (RCS) curve modeling. Additionally, subgroup and sensitivity analyses were conducted to assess the robustness of these findings.
resultsThe median age of the 771 patients was 66.6 years, with 173 (22.4%) developing AKI. A positive linear association was observed between the AIP and the risk of AKI. Specifically, each 0.1-unit increase in AIP was associated with a 10% higher risk of AKI (OR = 1.10, 95% CI: 1.05-1.15, P < 0.001). Sensitivity analyses after excluding patients with renal infections showed that AIP remained associated with the risk of acute kidney injury. Stratified analyses showed no significant interactions (all P for interaction > 0.05) in gender, age, BMI, SOFA score, GCS score, presence of other diseases (diabetes mellitus, chronic obstructive pulmonary disease, congestive heart failure).
conclusionsFor septic patients, the relationship between AIP and risk of AKI was positively linear, with higher AIP indicating higher risk of AKI.
