The trial began on 18 March 2012 and ended on 8 September 2015. It thus lasted almost 41 months. A total of 100 patients were enrolled in this study (Figure 2). Of these patients, 40 were assigned to the study group and 45 were assigned to the control group. All of these 85 patients had medical followup by telephone for 28 days. Three patients were lost to followup in the control group. Thirteen patients in the study group and 10 patients in the control group voluntarily terminated treatment for personal reasons such as financial burdens or poverty in family members. The renouncement rate of voluntary patient self-termination of treatment was not significantly different in the two groups (Table 3).
