A meta-analysis of randomized controlled trials on atenolol's impact on postoperative atrial fibrillation in adults undergoing cardiac surgery.

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
Prior research has conducted a limited number of studies on the efficacy of atenolol in preventing atrial fibrillation following cardiac surgery (CS). Consequently, a comprehensive evaluation and meta-analysis were undertaken to assess the effectiveness and safety of atenolol in patients undergoing CS for the prevention of postoperative atrial fibrillation (POAF). A meta-analysis of randomized controlled trials was performed. Searches were conducted across multiple databases up to December 1, 2024. The primary focus was the incidence of POAF. Risk ratios (RRs) for treatment effects on dichotomous variables were calculated. The data analysis encompassed 6 randomized controlled trials involving a total of 870 patients. The meta-analysis revealed that atenolol significantly reduces the incidence of POAF in adult patients undergoing CS (RR, 0.55; 95% confidence interval [CI]: 0.32-0.93; P = .03) with moderate heterogeneity (I2 = 57%; P = .10). Atenolol did not demonstrate superiority over sotalol in reducing POAF (RR, 2.39; 95% CI: 1.41-4.04; P = .001) with moderate heterogeneity (I2 = 40%; P = .19). Furthermore, no significant difference was observed between atenolol and the control group (comprising propafenone, metoprolol, nebivolol, and digoxin) in the prevention of POAF (RR, 1.28; 95% CI: 0.76-2.16; P = .35) with moderate heterogeneity (I2 = 43%; P = .15). Recent studies suggest that atenolol could be a safe and effective intervention for the prevention of POAF in adult patients undergoing CS.
