Development of a Nomogram to Classify In-Hospital Atrial Fibrillation Among Patients Hospitalized With Acute Myocardial Infarction: A Retrospective Case-Control Study.
Article in Reviews in cardiovascular medicine, 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
Background: Previous studies on acute myocardial infarction (AMI) complicated by atrial fibrillation (AF) have mainly focused on anatomy or underlying disease state, and its prognostic predictors have not been fully explored. Therefore, there is a need for an effective prognosis model for patients with AMI-AF. Methods: We retrospectively selected 126 patients with acute myocardial infarction complicated with AF hospitalized in Beijing Anzhen Hospital from January 2020 to December 2024 as the case group, and 1719 patients without AF as the control group. The clinical characteristics and laboratory test results of the two groups were compared to determine independent risk factors for AF in patients with acute myocardial infarction. The predictive performance of the model was evaluated by plotting Receiver Operating Characteristic (ROC) for each independent predictor. For the combined model, we used R software to build pattern plots, calibration plots, and Decision Curve Analysis (DCA) based on a multivariate logistic regression model. Results: Multivariate Logistic regression analysis showed that older age (Odds Ratio (OR) = 1.067, 95% CI: 1.044-1.092), longer hospitalization days (OR = 1.039, 95% CI: 1.013-1.066). The AUCs for age, hospitalization days, history of coronary heart disease, heart rate, International Normalized Ratio (INR), Hemoglobin, and mean platelet volume were 0.721, 0.663, 0.577, 0.614, 0.688, 0.438, and 0.607. The AUC of nomogram model for predicting AF in AMI patients was 0.833 (95% CI: 0.796-0.870, Conclusions: Multivariable prediction model has good prediction effect. The variables in this nomogram model are easily obtained in clinical practice and can provide reference for individualized prediction of AF in AMI patients.
