Early menopause as an independent risk factor for postoperative atrial fibrillation in women undergoing coronary artery bypass grafting: a retrospective 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
backgroundEarly menopause is considered directly related to the occurrence of isolated atrial fibrillation. In this study, we aim to explore the relationship between early menopause and the incidence of postoperative atrial fibrillation (POAF) occurring following coronary artery bypass grafting (CABG).
methodThis retrospective cohort study included patients who underwent CABG at Beijing Anzhen Hospital from January 2020 to December 2023. Patients were divided into two cohorts: early menopausal individuals (age < 45) and non-early menopausal individuals (age ≥ 45). Baseline characteristic disparities were adjusted via including all baseline variables with an standardized mean difference (SMD) > 0.1 as covariates in the inverse probability of treatment weighting (IPTW) analysis. The correlation between menopausal age and the occurrence of POAF was analyzed utilizing logistic regression and restricted cubic spline (RCS).
resultsAmong the 1825 female patients who underwent CABG in this study, 537 developed POAF. After IPTW analysis to control for baseline variables, it was found that the incidence of POAF in the early menopause group was significantly higher than in the non-early menopause group (42.1% vs. 28.2%). Logistic regression analysis showed that early menopause was associated with an increased risk of POAF (adjusted OR: 1.76, 95% CI: 1.30-2.38, p < 0.001). RCS analysis also confirmed our hypothesis, showing that early menopause is associated with an increased risk of POAF.
conclusionFemale CABG patients with early menopause have a higher incidence of POAF compared to those without early menopause. Additionally, the younger the age at menopause, the higher the risk of developing POAF. These findings suggest that menopausal age should be considered in preoperative risk stratification, and early menopausal women may benefit from targeted monitoring or preventive strategies to reduce POAF risk.
