Plus–minus values are means±SD. The treatment groups differed significantly in log-linear analyses or ANCOVAs, except in immediate response rate. Values with different letter superscripts for the same variable indicate that the corresponding treatment groups differed significantly from each other in post hoc pair-wise comparisons (P<0.05). Groups did not differ if they shared a superscript letter.

Declared a priori as a primary efficacy outcome measure.
