结局指标
主要结局
Percentage of Days without Symptoms of Heartburn
时间窗: Up to Week 4
Heartburn symptoms were collected by participant diaries. Participants recorded the presence and severity (Without symptom [No symptom: 0, No hindrance to daily activities: 1], With symptom [Mild: 2, Moderate: 3, Severe: 4]) of heartburn in a daily participant diary. The score range was 0-4, with the higher scores reflecting the greater severity. Reported data was the percentage of days for each group, calculated by the number of days without heartburn divided by the number of days of treatment period.
Cumulative Rate of Improvement in Symptoms of Heartburn
时间窗: Day 0 to Day 24
Heartburn symptoms were collected by participant diaries. Participants recorded the presence and severity (Without symptom [No symptom: 0, No hindrance to daily activities: 1], With symptom [Mild: 2, Moderate: 3, Severe: 4]) of heartburn in a daily participant diary. The score range was 0-4, with the higher scores reflecting the greater severity. Cumulative rate of improvement was calculated as percentage of participants who experienced symptom improvement. Symptom improvement was defined as symptoms experienced on less than 2 days of the last 7 days.
Severity of Symptoms of Heartburn
时间窗: Up to Week 4
Participants recorded the presence and severity (Without symptom [No symptom: 0, No hindrance to daily activities: 1], With symptom [Mild: 2, Moderate: 3, Severe: 4]) of heartburn in a daily participant diary. The score range was 0-4, with the higher scores reflecting the greater severity. The severity of heartburn was calculated by the number of severity score in daily diaries.
