  • ELX, eluxadoline; LS, least squares; MPC, maximum pupil constriction; NS, not significant; OXY IR, oxycodone immediate release; PBO, placebo.

  • a P values are for pairwise comparisons of LS mean differences between treatments.

  • b P values are for pairwise comparisons of median differences between treatments. Both assessed using the Wilcoxon signed-rank test.
