FIG. 5. Kaplan-Meier survival curves to show effect of feedback (uNTX) based on persistence (n = 2302). Because the reinforcement message delivered at wk 13 and 25 could be different for the same patient, graphical representation of the model was assessed by classifying the patients in RE+ into three message categories: 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%; and poor, at least one uNTX increase more than 30% at wk 10 or 22. The numbers of visits corresponding to good uNTX response (1369 visits) or stable uNTX response (639 visits) were higher than those corresponding to a poor uNTX response (98 visits).
