Peak atrial longitudinal strain as a predictor of postoperative atrial fibrillation in isolated coronary artery bypass grafting: Insights from a single-centre study in Indonesia.
Article in Global cardiology science & practice, 2025. 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
backgroundPostoperative atrial fibrillation (POAF) is a frequent complication in patients undergoing coronary artery bypass grafting (CABG) and contributes to increased morbidity and mortality. Identifying accurate preoperative predictors for POAF remains a clinical challenge.
objectivesThis study aimed to evaluate the predictive value of preoperative peak atrial longitudinal strain (PALS) for POAF in patients undergoing isolated CABG.
methodsThis prospective cohort study was conducted from May to October 2024. A total of 58 adult patients undergoing isolated CABG were consecutively enrolled. PALS measurement was performed preoperatively using speckle tracking echocardiography. Patients were followed for 30 days postoperatively to monitor POAF occurrence. Statistical analyses in this study included ROC curve, Kaplan-Meier, and Cox regression.
resultsOf the 58 patients, 30 patients had PALS <28% and 28 patients had PALS ≥28%. The incidence of POAF was significantly higher in the low PALS group (53.3% vs 10.7%,
conclusionPreoperative PALS < 28% is a strong predictor of POAF in patients undergoing isolated CABG. PALS assessment and surgical technique can optimize risk stratification and POAF prevention strategies.
