*PCV=proportional change in variance; it is the share of the total variance from the empty model (reference) that is attributable to the variables included in each model.

†MRR=median rate ratio; it can be interpreted as the median value of the rate ratio between the village at highest risk and the village at lowest risk when randomly picking out two villages.
