SOstGp1 & FnOstGp1 = groups with normal spine and hip bone density, (T-scores ≥ − 1.00).
SOstGp2 & FnOstGp2 = groups with osteoporosis of spine and femoral neck (T-scores < − 2.5).
Osteoporosis prevalence was tested for significance using the Fisher Exact Test.
Comparisons of Sbmd and Fnbmd among the 3 BMI groups were carried out using the multilinear regression analysis with, age, METmin, PBF as covariates.
