A statistician will be contracted to independently oversee the analysis of study results. The intention-to-treat principal will be used to analyze all data. Data will be analyzed using descriptive statistics. Categorical data will be presented as frequency and percentage frequency of occurrence. Continuous data will be presented as medians with ranges and interquartile ranges (IQRs). Adverse effects will be described as frequency of occurrence with 95% confidence intervals. A p-value of 0.05 will be considered statistically significant.
