Flow diagram: Study participant eligibility assessment, enrollment, group allocation and analysis. People recruited for the study were assessed and those deemed eligible were enrolled. Subjects were randomized into one of two beverage groups. Bottles of the two beverages, cranberry and placebo, were received from Ocean Spray Cranberries, Inc. and labeled either #638 or #246. Subjects and investigators were blinded regarding the treatment groups. Statistical analysis was performed on data from all subjects completing the study. Investigators were unblinded (cranberry beverage: #638; placebo beverage: #246) following completion of the data analysis.
