Plotted are the mean (+ S.E.M. error bar) visual analog scores (VAS) for pain using a patient-marked 100 mm line with 0 = no pain and 100 = worst pain. Repeated measures ANOVA as indicated for the P group (shaded bar) and BM group (solid bar). Number of subjects interviewed at each time point is indicated above each set of bars. Number lower than enrolled reflects unresponsive subjects at early postoperative times and subjects discharged early for later time points. Repeated measures ANOVA showed a significant within subject effect of time (F = 7.9921 (with Huynh-Feldt correction) ; P = 0.02) but the interaction between time and treatment were not significant (F = 0.453; P = 0.84).
