[number of patients per patient group with non-missing PROCAM; proportion of all patients with non-missing PROCAM].
PROCAM risk in relation to BMI and waist circumference [12]. N means number of patients with non-missing PROCAM in each cell; % of inner 9 cells adds up to 100%; the figure displayed is the risk for cardiovascular events for the next 10 years calculated with the PROCAM score (standardized for age). Crude/age-standardized mean are reported. * means that the total N in this cell is 30 or below and therefore the direct age standardization may have led to unreliable results.
