Validated nomogram for predicting 30-day mortality of SAE. When using it, drawing a vertical line from each variables upward to the points and then recording the corresponding points (i.e., “RDW = 14” = 20 points). The point of each variable was then summed up to obtain a total score that corresponds to a predicted probability of 30-day death at the bottom of the nomogram
