An Evaluation of Four Predictive Scores for New Onset Atrial Fibrillation After Cardiac Surgery in a Tertiary Cardiac Centre.
Article in ANZ journal of surgery. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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, leading to increased mortality, morbidity, and length of stay. Various predictive indices have been validated to identify patients at risk of developing POAF. This study aimed to compare the discriminative ability of four bedside indices that predict POAF in cardiac surgical patients.
methodA total of 2465 consecutive patients who underwent cardiac surgery at an Australian tertiary hospital between 29 December 2015, and 31 December 2022, were retrospectively analysed. Exclusion criteria included pre-existing atrial fibrillation and transcatheter interventions. The area under the receiver-operating characteristic curve (AUC-ROC) analysis and Hosmer-Lemeshow calibration were performed to compare discriminative abilities. A logistic regression model was constructed to evaluate independent risk factors for developing POAF.
resultsOlder patients (aged > 69) were more likely to develop POAF compared to younger age groups (p < 0.001). The Atrial Fibrillation Risk Index, CHA
conclusionAlthough previously validated in various cohorts, the four bedside predictive indices demonstrated poor discriminative ability and limited generalizability to our tertiary-hospital cohort.
