Nomogram for prediction of related risk factors and the possibility of MetS. All independent risk factors with statistical significance (sex, age, SAS score, SCH, alcohol and cigarette consumption) were included and unified into one risk factor MRRF (MetS-related risk factor). The 1st line is the standard scale compared to each downward line (2–7), by which a specific score of each line could be calculated. Then sum of 6 lines (scores) will be put on the 8th line as the total points, and projected to the last line, which stands for the possibility of MetS. The C-indices of predicting MetS nomogram were 0.705 (95% CI: 0.696, 0.714) and 0.728 (95% CI: 0.701, 0.754) in training and testing panel respectively, indicating that the proposed nomogram of MetS prediction performed well in all MetS subjects.
