NS: statistically not significant (P ≥ 0.006) when comparing CAD males versus CAD females.
P‐value refers to statistical comparison between CAD‐male and CAD‐female groups.
*P < 0.004 identifying significant differences (unpaired Student's t‐test with Bonferroni's method) when comparing CAD patients versus control subjects, CAD males versus control males, and CAD females versus control females.
