Notes. GSS, Sleep length, SWPAQ S, w, and M: Main effect of the second factor and/or interaction (1. Gender and 2. Region) was significant for GSS and other included variables. For CSS, the list of covariates was the same as in Table 4. For other variables, GSS was included instead of an analyzed variable. Refer also notes to Table 5.
