Interpretation of results: if eβ > 1, the odds of higher QoL are greater, whereas when eβ < 1 low QoL is more probable.

^a) premenopause at both baseline and follow up
^b) transition from premenopause to peri- or postmenopause
^c) perimenopause or postmenopause both at baseline and follow-up; from perimenopause at baseline to postmenopause at follow-up
