Percent Reduction From Baseline in Cough Frequency (Cough Events Per Day) to the Average of Week 8 Through Week 12
Query!
Assessment method [1]
0
0
Percent reduction in cough frequency was analyzed with a mixed effects model for repeated measures (MMRM), with change from baseline at each post-baseline visit on the natural log scale as the dependent variable. The percent reduction was estimated as 100% × (1-exponential form of LS mean change estimate from the MMRM).
