Pearson’s correlation coefficients (r) and partial correlation coefficients (P-r) after adjustment for age and body mass index are shown.
OPG: osteoprotegerin, TGF-β: transforming growth factor-beta, BDR: bone mineral density decrease rate, PA: posteroanterior spine, FN: femoral neck, Hip: total hip, and RUUD: radius + ulna ultradistal.
