Feature selection
embolism
EMBOLISM, INFLAMMATION
To ensure the robustness of the ML classification model, features were selected if they: (i) characterized the cardiac function, risk of systemic embolism or the level of inflammation, or (ii) promoted the occurrence and development of AF. Laboratory and echocardiographic characteristics were considered as missing values if they were not collected four weeks prior to the ablation procedure. Characteristics with more than 15% of missing values were excluded. Finally, 30 features were selected. Details of the features are presented in Additional file
