(A) Nomogram for predicting RS. A weighted point (from 0 to 100) was given to each risk factor that could be found in the line marked with “Points” on the top. The total points of all risk factors of each patient could be used to predict the probability of RS-free for the patient by drawing a vertical line from the total points x-axis to the probability (the higher the total points, the less the probability for RS-free). The scores for daily fruit consumption, housework, HDL, good sleep, light diet and smoking could be obtained individually by drawing a line from the corresponding value up to the “points line”. The “total points” was calculated as the sum of the individual scores of each of the six variables included in the nomogram. (B) Calibration curves of the nomogram to predict RS-free at 1 year. The actual RS-fee rate for patients was plotted on the y-axis, and nomogram predicted probability for the same patients was plotted on the x-axis. There was a nice match between the actual RS-free rate and the predicted probability.

Abbreviations: HDL, high-density lipoprotein; RS, recurrent stroke.
