Values are LSmean ± SE (all such values). ^†Student’s t-test was used to compare differences between the groups. ^‡Linear mixed-effect model adjusted with total volatile sulfur compound, alcohol drinker and alcohol amount at baseline was used to analyze the effects of group* week. ^§Linear mixed-effect model adjusted with total volatile sulfur compound, alcohol drinker and alcohol amount at baseline was used to analyze the difference within each group.
