  1. Abbreviations: HDL-C, high-density lipoprotein; LDL-C, low-density lipoprotein; TC, total cholesterol; TG, triglyceride.
  2. aANOVA P-value <0.05 indicates significant association with sleep duration when comparing the group to all other sleep duration groups within the lipid variable.
  3. bANOVA P-value <0.01 indicates significant association with sleep duration when comparing the group to all other sleep duration groups within the lipid variable.
  4. cANOVA P-value <0.001 indicates significant association with sleep duration when comparing the group to all other sleep duration groups within the lipid variable.
