Sample size calculation was based a previous study on fast track hysterectomy, which showed a difference in return to work of 4 days. 62 women in each group is needed with standard deviation ±8 and a power of 80%. To include those not working, we calculated that with an expected visual analog pain score of 0.86 ±0.2 and 62 in each group the sample was sufficient to detect of difference of 0.1 in visual analog pain score with a power of 80%. All calculation are based on two-sided testing with alpha of 0.05.
