结局指标
主要结局
Percent Change From Baseline to Week 8 in Weekly Heartburn Severity Score (WHSS)
时间窗: Baseline (derived from the eDiary daily data collected from 7 days before randomization up to the time of randomization), Week 8
The WHSS for an analysis week was defined as the average of available DHSS during that week. DHSS was defined as the maximum on a 6-point scale (0=Did Not Have, 1=Very Mild, 2=Mild, 3=Moderate, 4=Moderately Severe, 5=Severe) of the 3 items measuring heartburn ( "Heartburn," "Burning feeling behind breastbone or in the center of the upper stomach," and "Pain behind breastbone or in the center of the upper stomach,") from a particular day. A negative change from Baseline indicates improvement.
