Serums OPG, TGF-β1, and TGF-β2 were independent variables; BDRs were dependent variables.
OPG: osteoprotegerin, TGF-β: transforming growth factor-beta, BDR: bone mineral density decrease rate, C: R square change, PA: posteroanterior spine, FN: femoral neck, Hip: total hip, and RUUD: radius + ulna ultradistal.
a –0.000.
bIndependent was excluded in this analysis.
