The relationships between the calcaneal BMD and MI in the subject groups

T-score group n Calcaneal T-score dependence on MI Calcaneal BMD (g cm−2) dependence on MI
T1 34 r = 0.2; p = 0.4 r = 0.2; p = 0.4
T2 65 r = 0.2; p = 0.3 r = 0.2; p = 0.2
T3 30 r = 0.1; p = 0.8 r = 0.1; p = 1.0
Total 129 r = 0.4; p < 0.001 r = 0.4; p < 0.001

BMD, bone mineral density; MI, mental index; T1, subjects with normal BMD (T-score > −1); T2, subjects with osteopaenia (−1 ≥ T-score > −2.5); T3, subjects with osteoporosis (T-score ≤ −2.5).
