where:
• In the nomogram in Figure 1 exercise scoring is the opposite of that shown in Table 2.
total score without triglycerides =
= SUM(points for the first 5 parameters)
total score with triglycerides =
= SUM(points for all 6 parameters)
Interpretation:
• minimum score for both scores: 0
• maximum score without triglycerides (non-laboratory): 33
• maximum score with triglycerides (laboratory-based): 37
• The higher the score the greater the risk for developing diabetes mellitus.
