Kaplan-Meier plot of time to rescue analgesia therapy. The data show the percentage of cats at each time point which had not received rescue therapy to control post-operative pain (defined as treatment failure). Time 0 was fixed as the time of post-surgical extubation. There was a lower frequency of treatment failure in the robenacoxib group compared to the placebo at 30 min and all subsequent times. P < 0.0001 with log-rank, Cox-Tarone and Gehan-Breslow tests
