Vitamin D supplementation during intensive care unit stay is associated with improved 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: Patients with vitamin D deficiency are susceptible to increased microbial infection and increased risk of mortality. However, whether vitamin D supplementation would improve their prognosis remains uncertain. Methods: We conducted a retrospective cohort study using data from MIMIC-IV database, a publicly available database containing clinical information on patients admitted to the ICU at Beth Israel Deaconess Medical Center (BIDMC) from 2008 to 2019. Adult patients with sepsis were included in the analysis. The exposure factor was vitamin D supplementation during the ICU stay. The primary outcome was 28-day all-cause mortality. Both propensity score matching (PSM) and stepwise regression analyses were employed to adjust for potential confounders. Results: A total of 20230 eligible patients were enrolled in the entire unmatched cohort, and 8710 patients were included in the matched cohort. In PSM analysis, the 28-day all-cause mortality rate was 14.04% (250/1780) in the vitamin D group and 22.31% (1546/6930) in the no vitamin D group. Vitamin D supplementation was associated with decreased 28-day all-cause mortality (HR, 0.56; 95% CI, 0.49-0.64; p < 0.001). Subgroup analyses showed consistent benefits regardless of the baseline vitamin D status (deficiency: HR, 0.70; 95% CI, 0.33-1.50; p = 0.36; insufficiency: HR, 0.10; 95% CI, 0.03-0.34; p < 0.001; sufficiency: HR, 0.33; 95% CI, 0.12-0.88; p = 0.03). Additionally, vitamin D supplementation was associated with decreased ICU mortality (OR, 0.37; 95% CI, 0.29-0.48; p < 0.001) and reduced in-hospital mortality (OR, 0.57; 95% CI, 0.48-0.68; p < 0.001). Sensitivity analysis using the unmatched cohort confirmed these findings (HR, 0.57; 95% CI, 0.43-0.76; p < 0.001). Conclusions: Vitamin D supplementation may reduce mortality in critically ill patients with sepsis. However, further high-quality prospective studies are still needed to validate these findings.
