Parameter Predicting Postoperative Atrial Fibrillation in Coronary Artery Bypass Grafting Patients: Triglyceride-Cholesterol-Body Weight Index.
Article in Arquivos brasileiros de cardiologia, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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 after cardiac surgery, particularly coronary artery bypass grafting (CABG). Despite advances in surgical techniques, POAF remains a significant cause of morbidity and mortality.
objectivesThis study investigates the potential of the Triglyceride-Cholesterol-Body weight Index (TCBI) as a predictor of POAF, focusing on the impact of nutritional status on surgical outcomes.
methodsThis retrospective study included 321 patients who underwent CABG surgery between January 2010 and January 2024. TCBI was calculated using preoperative blood samples and compared between those who developed POAF and those who did not. Statistical analyses, including Cox regression and ROC analysis, were performed to assess the predictive value of TCBI for POAF. P<0.05 was considered statistically significant.
resultsPatients who developed POAF had significantly lower TCBI (1790.8 ± 689, 3413.3±1232, p<0.001, respectively) levels compared to those without POAF. Also, age (p<0.001), the frequency of hypertension (p=0.009), CRP (p=0.03), and WBC (p=0.02) values were also significantly higher in patients who developed POAF.TCBI was identified as an independent predictor of POAF (OR: 0.998, 95% CI: 0.997-0.999, p<0.001), with a cut-off value of 1932.4 predicting POAF with 75% sensitivity and 78% specificity.
conclusionThe TCBI is a reliable indicator for predicting POAF in CABG patients. Preoperative identification of patients with low TCBI could lead to targeted interventions, reducing postoperative complications and improving outcomes. Optimizing nutritional status before surgery may mitigate the risk of POAF.
