A-fib atrial fibrillation.

Based on the results of all the univariable Cox Hazard Proportion Analysis model, we adjusted the confounding factors and performed a multivariable Cox proportional hazard regression analysis.

Percent proportion is indicated in () except for the 95% confidence interval.
