Efficacy
Statistical methods / analysis
The sample size calculated to be 170 patients with 85 patients in each study arm to have 90% power to detect difference of a 25% of response treatment between the 2 antibiotics cohorts (25% to 50%) at the 5% alpha (significance) level. Because of missing data and losses to follow-up, an additional 30 subjects will be needed (100 in each arm) for a total of 200 subjects.

The data will be collected in hard copy with coding number for each participant. Then it will be entered in STATA version 13.1 for analysis. Descriptive statistics will be used to describe the data. For categorical variables, frequencies and percentages will be reported. Differences between groups will be analysed using Pearson’s c2 tests. For continuous variables, mean and standard deviation will be used to present the data while analysis will be performed using Student’s t-tests. For non-normal distributed continuous variables, median and interquartile range (IQR) will be used to summarize the data and analysis performed using Wilcoxon-Mann-Whitney tests. An a priory two-tailed level of significance will be set at <0.05 level.
