Percent change in spine bone mineral density (BMD) after 24 months of risedronate grouped by percentage decrease in bone turnover markers (in tertiles) at 12 months. Results as mean ± SEM. For CTX (overall ANOVA pairwise comparison p<0.05), group a) lowest tertile (<13%), b) middle tertile (13 – <43%) and c) highest tertile (>43% decrease). For P1NP (overall ANOVA pairwise comparison p<0.01), group d) lowest tertile (<37%), e) middle tertile (37–50%), and f) highest tertile (>50% decrease). Significance between tertiles: a vs. c (p<0.01), b vs. c (p<0.05), d vs. e (p<0.05), d vs. f (p<0.01), and e vs. f (p=0.07).
