Kaplan-Meier survival curves showing the effect of providing bone turnover marker results (urinary n telopeptide, or uNTX) on persistence (n = 2302). Bone turnover marker response was categorized as good (more than 30% decrease from baseline in uNTX at wk 10 and 22); stable, at least one stable uNTX response at wk 10 or 22 and no increase in uNTX more than 30%; or poor, at least one uNTX increase more than 30% at wk 10 or 22. The numbers of patient visits with a good (1369 visits) or stable uNTX response (639 visits) was higher than the number of visits with a poor response (98 visits).
