All the upper bounds of the 90% confidence intervals of these changes were below the predefined clinically significant threshold. Symmetry analysis found no differences in the proportion of participants with \u0394SDLP exceeding the threshold in either impairing or improving from 0 cm, at vornorexant 10 mg on Days 2 and 9 and 20 mg on Day 9.
