Statin use during intensive care unit stay is associated with improved clinical outcomes in critically ill patients with sepsis: a cohort study.

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
Background: Despite early goal-directed therapy, sepsis mortality remains high. Statins exhibit pleiotropic effects, including anti-inflammatory and antimicrobial properties, which may be beneficial during sepsis. Objective: To determine whether statins could improve the clinical outcomes in patients with sepsis. Methods: We conducted a retrospective cohort study using data from the Medical Information Mart in Intensive Care-IV (MIMIC-IV) database. Adult patients with sepsis were included in the analysis. The exposure factor of this study was statin use during the Intensive Care Unit (ICU) stay. The primary outcome was 28-day all-cause mortality. The secondary outcomes were ICU and in-hospital mortality, length of ICU stay and hospital stay, duration of mechanical ventilation (MV) and continuous renal replacement therapy (CRRT). Both propensity score matching (PSM) and stepwise regression analyses were employed to adjust for potential confounders. Results: The unmatched cohort comprised 20230 eligible patients, with 8972 patients in the statin group and 11258 in the no statin group. Propensity score matching generated balanced cohorts with 6070 patients in each group. Post-PSM analysis revealed significantly lower 28-day all-cause mortality in the statin group (14.3% [870/6070]) compared to the no statin group (23.4% [1421/6070]). Statin use was associated with decreased 28-day all-cause mortality (hazard ratio [HR], 0.56; 95% confidence interval [CI], 0.52-0.61; p < 0.001). In subgroup analysis, this beneficial effect was consistent across the different baseline characteristics of patients. Additionally, statin use was associated with decreased ICU mortality (odds ratio [OR], 0.43; 95% CI, 0.37-0.49; p < 0.001) and reduced in-hospital mortality (OR, 0.50; 95% CI, 0.45-0.57; p < 0.001). Sensitivity analysis using the unmatched cohort also showed a significant difference in 28-day all-cause mortality between the statin group and the no statin group (HR, 0.56; 95% CI, 0.52-0.61; p < 0.001). Conclusion: Statins were associated with decreased mortality in critically ill patients with sepsis. Further high-quality prospective studies are still needed to verify our findings.
