Correlation between procollagen type I N propeptide (PINP) change from baseline to 1 month (mcg/L) and percent change in lumbar spine bone mineral density (BMD) from baseline to 12 months in a trial of Japanese patients with osteoporosis randomized to teriparatide or to placebo. A vertical line represents a PINP increase of 10 mcg/L, and a horizontal line represents a lumbar spine BMD increase of 3 %. Adapted from Tsujimoto and colleagues [39]
