Sex Differences in Long-term Outcomes Following Coronary Artery Bypass Grafting: A Nationwide Population-Based Propensity Score-Matched Cohort Study.
Article in Journal of Korean medical science, 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
backgroundThe relationship between sex differences and clinical outcomes following coronary artery bypass grafting (CABG) has been highlighted in several studies. However, these studies were mostly based on single- or multi-center data, and only a few meta-analyses examined long-term outcomes. To address this limitation, we conducted a nationwide population-based cohort study in Korea.
methodsA total of 48,206 adult patients who underwent first-time isolated CABG between January 2005 and December 2021 were enrolled. To address potential confounding, propensity score (PS) matching was conducted. The primary outcome was overall mortality.
resultsAmong the enrolled patients, 12,270 (25.5%) were female. The median age of the overall cohort was 66.0 years (interquartile range [IQR], 59.0-72.0), with female patients (median, 69.0; IQR, 63.0-75.0) being significantly older than male patients (
conclusionIn this nationwide population-based PS-matched cohort study, female patients who underwent isolated CABG exhibited significantly lower overall mortality compared to male patients during long-term follow-up, whereas no significant difference was observed in cardiac-related mortality.
