  1. T1, non-HDLc/HDLc: 0.41–2.35; T2, non-HDLc/HDLc: 2.36–3.36; T3, non-HDLc/HDLc: 3.37–5.98. Continuous data are shown as the mean ± standard deviation or median (interquartile), and categorical data are shown as n (%). For categorical variables, P value was calculated by χ2 or Fisher’s exact test. For continuous variables, P value was calculated by one-way ANOVA or Kruskal–Wallis test
