The survival nomogram for predicting in-hospital mortality of critically ill patients with atrial fibrillation. When using it, drawing a vertical line from each variable upward to the points and then recording the corresponding points (i.e., “age > 60 years old” = 0.8 points). The point of each variable was then summed up to obtain a total score that corresponds to a predicted probability of in-hospital mortality at the bottom of the nomogram
