β: associated coefficient of the GLMM regression

SIR: standardized incidence ratio

^a: number of patients undergoing retreatment/standard deviation of retreatment

^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
