  1. Goodness of fit test: Hosmer Lemeshow, Chi 2 (8df) = 7,36, p = 0,49. *aOR adjusted odds ratio; OR odds ratio. Intra-class correlation coefficients for each outcome were as follows: age:0.02, Gender:0.001, stunting:0.08, slide microscopy positive:0.011. All p values are adjusted for clustering by robust standard errors.
