Time on study (9.1 [3.8] weeks, p=0.52) and rate of study completion (85 of 150 subjects, p=0.46) did not differ among treatment groups, nor did the reasons for termination (shown in Figure 1, p=0.83). Mean rate of medication compliance, defined as number of pills taken divided by number prescribed during study participation, was 96.2% and did not differ among groups (p=0.79). Groups were similar in their ability to correctly guess the identity of their medication when asked to do so upon study completion (59% gabapentin, 45% placebo, p=0.21).
