 All the baseline data variables collected will be summarized by group and overall, and also by site. Among the statistical summary statistics considered for presentation for continuous measures in summary tables will be the mean, median, minima and maxima, lower and upper quartiles, and standard deviation. Categorical variables will be summarized using counts and percentages. As the PWDs will be assigned to the intervention and control using random allocation it is known in advance that any differences between these groups at baseline will be as a result of chance and so no formal comparison of the groups using statistical significance tests will be carried out at baseline.
