HCC, hospital-based case-control study; PCC, population-based case-control study; ref, reference; WHR, waist-to-hip ratio.
2
Dichotomized variable based on means for controls: premenopausal women: BMI:24.83 kg/m2, WHR: 0.88; postmenopausal women: BMI: 25.03 kg/m2, WHR: 0.90.
3
Age < 50 y (unknown menopausal status).
4
Age ≥50 y (unknown menopausal status).
5
Adebamowo et al. (68, 69) were earlier reports for Ogundiran et al. (66, 70) and were therefore not included in the table because they correspond to the same study.
6
Adjusted for age only.
7
Further adjusted for BMI.
