  27. 27. Statistical Analysis <ul><li>For continuous data, mean and standard deviation were used to summarize baseline and week 52 results and to report the mean and 95% confidence interval for the change at week 52 compared to baseline. We also assessed the difference of changes between the groups in mean and 95% confidence intervals. </li></ul><ul><li>For the binary data, event count and proportions were reported for both visits and the change of week 52 comparing to the baseline was measured by the proportional difference and its confidence interval. </li></ul><ul><li>To test for significant difference from baseline, the paired t-test was applied to continuous data and McNemar’s test for the binary data. To compare the difference of change between the groups, the Z-test was performed. </li></ul>
