Postoperative atrial fibrillation following cardiac surgery in severe obesity: the added value of waist circumference.
Article in International journal of obesity (2005), 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
introductionObesity is an independent risk factor for postoperative atrial fibrillation (POAF) after coronary artery bypass grafting (CABG) surgery. POAF in patients with severe obesity (body mass index [BMI] ≥ 35 kg/m
aimTo evaluate the risk of POAF, the role of WC in predicting POAF and postoperative complications after CABG surgery in severe obesity.
methodsOur cohort included 7995 patients undergoing CABG surgery (2006-19). POAF risk was compared across BMI and WC categories. In patients with severe obesity, the association of an increase in WC with POAF risk was assessed.
results763 (9.5%) patients had a BMI ≥ 35 kg/m
conclusionsSevere obesity increases the risk of POAF after CABG surgery. In this subgroup, elevated WC may provide additional prognostic value independently of BMI. Since POAF is associated with adverse long-term outcomes, abdominal obesity by measurement of WC should be assessed and targeted even in patient with severe obesity. Central Illustration Increasing waist circumference associated with increased atrial fibrillation risk post coronary artery bypass grafting. Bar graph of the unadjusted absolute risk and 95% confidence interval of postoperative atrial fibrillation for each tertile of waist circumference per body mass index category. Comparison of postoperative atrial fibrillation risk with chi-square test showing an increasing risk of postoperative atrial fibrillation related to increasing waist circumference within each body mass index category. ABBREVIATIONS: BMI, body mass index; POAF, postoperative atrial fibrillation; WC, waist circumference.
