  1. Comparison were made for all groups (p) and between groups by using post-hoc test with Bonferroni correction (corrected p value threshold: < 0.0083). All comparison remains significant in post-hoc test, excepted between No OSA groups for sex, between OSA groups for apnoea + hypopnoea index (AHI) and between sleepy groups for ESS.
