  1. Results obtained from the multinomial logistic regression. Cluster 7 with the lowest mean number of MRFs (Table 2) was considered as reference group in multinomial regression analysis
  2. MRFS metabolic risk factors, OR odds ratio, CI confidence interval
  3. *P values are based on statistical significance of OR
