Table 1. The mean and standard deviation values of the variables for the normal, osteopenia, and PMO groups.

BMI: body mass index; BMD: bone mineral density; PDW: platelet distribution width; MPV: mean platelet volume; PCT: procalcitonin; ESR: erythrocyte sedimentation rate; CRP: C-reactive protein; NLR: neutrophil-to-lymphocyte ratio; PLR: platelet-to-lymphocyte ratio; MLR: monocyte-to-lymphocyte ratio; SII: systemic immune inflammation index; PMO: postmenopausal osteoporosis.
