Adipokine levels were dichotomized as high\/low using median values. Incident osteoporotic fracture was defined based on published algorithms using diagnostic codes and confirmed by chart review.

After adjustment, the risk of incident fracture was increased for high levels of leptin (hazard ratio [HR] = 1.47; 95% confidence interval [CI] 1.15\u20131.90;\n                      <jats:italic>P<\/jats:italic>\n                      = 0.003), FGF\u201021 [HR = 1.39; 95% CI 1.16\u20131.67;\n                      <jats:italic>P<\/jats:italic>\n                      &lt; 0.001), and adiponectin (HR = 1.21; 95% CI 0.94\u20131.55), with the latter not achieving significance (\n                      <jats:italic>P<\/jats:italic>\n                      = 0.13).
