^b: number of patients with relapse + number of patients with treatment failure/standard deviation of relapse and treatment failure
^c :number of households with more than one case/standard deviation of households with more than one case
^d: number of patients lost to follow-up/standard deviation of patients lost to follow-up
^e: distance from patient's residence to DTC/standard deviation of patient's residence to DTC
