Table 5: The value of p was derived from Multivariate logistic regression analysis with successive steps backward (conditional) method. Statistical significance p values are shown in bold (p < 0.05).

Abbreviations: HDL c, High-density lipoprotein cholesterol; LDL c, Low-density lipoprotein cholesterol; OR, odds ratio; SD, standard deviation; Tg/HDL c, Triglyceride/High-density lipoprotein cholesterol ratio.
