¹P value is reported based on the one-way ANOVA for normally distributed continuous variables and Kruskal–Wallis for non-normally distributed continuous variables. A Bonferroni post hoc test was used to show differences between groups
^aSignificant difference with MHNW
^bSignificant difference with MUNW
^cSignificant difference with MHO
^dSignificant difference with MUO
²ANCOVA adjusted for age, sex, waist circumference, smoking, and physical activity
