Statistical analysis description |
Sample size was calculated by nQuery Advisor® 7.0 based on the primary endpoint (NRS scale) and the cross-over study-design. According to previous literature, a pain reduction by 20% upon verum compared to placebo and a common standard deviation (SD) for the period differences of 2.5 seemed to be achievable and would have been clinical meaningful

Notes [1] - Sample size was calculated by nQuery Advisor® 7.0 based on the primary endpoint (NRS scale) and the cross-over study-design. According to previous literature, a pain reduction by 20% upon verum compared to placebo and a common standard deviation (SD) for the period differences of 2.5 seemed to be achievable and would have been clinical meaningful [2] - We calculated that 21 patients per sequence group were sufficient to show this effect (e.g. a reduction of 20% from 6 points to 4.8 points) with a power of 85% and a two-sided type-I-error of 0.05 using a paired t-test for 2x2 crossover designs |
