Results obtained from the multinomial logistic regression. Cluster 1 with the lowest mean number of MRFs (Table 3) was considered as reference group in multinomial regression analysis

MRFS metabolic risk factors, OR odds ratio, CI confidence interval

*P values are based on statistical significance of OR
