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
backgroundPostoperative atrial fibrillation (POAF) is a common complication following coronary artery bypass grafting (CABG), contributing to increased morbidity, prolonged hospitalization, and elevated healthcare costs. Emerging evidence suggests that vitamin D (Vit. D), via its anti-inflammatory effects and modulation of the renin-angiotensin-aldosterone system (RAAS), may have a cardioprotective role.
objectiveThis systematic review and meta-analysis aimed to evaluate the efficacy of preoperative Vit. D supplementation in reducing the incidence of POAF among CABG patients, with a focus on populations with Vit. D deficiency and insufficiency.
methodsOur study was conducted in accordance with the PRISMA 2020 Guidelines. The electronic databases PubMed, Cochrane Library and Google Scholar were searched from 2014 to 2024. Randomized controlled trials and retrospective observational studies involving adult subjects, evaluating Vit. D deficient and/or insufficient patients who have undergone CABG and received Vit. D supplementation in addition to standard care, compared to patients receiving standard care alone or with placebo, and reporting incidence of new-onset POAF were included. Statistical analysis was performed using RevMan v5.4 software, utilizing a random effects model with heterogeneity assessed using the I
resultsA total of four randomized controlled trials were included in our study, evaluating a sample size of 694 (Vitamin D group- 342, Control group- 352; mean age- 61.8 years, 42.6% females). Our meta-analysis revealed that preoperative Vit. D supplementation significantly reduced the incidence of POAF in post-CABG patients with sub-optimal Vit. D levels (RR = 0.55, 95% CI: 0.40-0.76, p = 0.0003, I
conclusionPreoperative Vit. D supplementation appears beneficial in reducing POAF risk in deficient CABG patients, but not in insufficient populations. These findings support targeted supplementation as a potential adjunct in perioperative care, though further large-scale studies are warranted to define optimal dosing strategies and broader applicability.
