1 · What the graph read from it

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.

2 · The registry

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

objectivesAtrial fibrillation is a common complication after heart surgery, potentially leading to chronic atrial fibrillation, heart failure and mortality. The aim of this study was to explore the relationship between preoperative interatrial block and the occurrence of postoperative atrial fibrillation.

methodsPerioperative 12-channel electrocardiographies of patients in sinus rhythm scheduled for heart surgery, including bypass and/or valve surgery, were analysed. Patients with pre-existing atrial fibrillation, amiodarone therapy, atrioventricular block II or III, or pacemaker were excluded from the study. Clinical parameters in patients with versus without atrial fibrillation were compared. To evaluate the association between interatrial block and postoperative atrial fibrillation, univariable and multivariable regression analyses were performed.

resultsOut of 2374 patients, 1350 were amenable to analysis. Postoperative atrial fibrillation was documented in 505 (37.4%) patients. In multivariable regression analysis, prediction models with and without interatrial block were established. Step-wise regression analysis identified interatrial block [2.64 (2.02; 3.46), P < 0.001), age [1.11 (1.03; 1.20), P = 0.007], EuroScore II [1.05 (1.03; 1.07), P < 0.001], pulmonary hypertension [1.91 (1.24; 2.97), P = 0.006], history of cardiogenic shock [2.05 (1.11; 3.87), P = 0.032], statins [1.66 (1.21; 2.27), P = 0.002], chronic obstructive pulmonary disease [2.11 (1.25; 3.65), P = 0.009] and cardiopulmonary bypass time [1.78 (1.04; 3.05), P = 0.047] as independent predictors for postoperative atrial fibrillation.

conclusionsPreoperative interatrial block was associated with a higher incidence of postoperative atrial fibrillation. Inclusion of electrocardiography-derived preoperative conduction disturbances can enhance risk stratification of postoperative atrial fibrillation after heart surgery.
