*Quasi-likelihood under the independence model criterion. This is a modification of the Akaike information criterion so that it can be applied to GEE regression models to assess goodness of fit of different models. A lower QIC term reflects a better-fitting regression model.
†One VHW joined the first cohort of VHWs later and is thus excluded from this analysis.
GEE, generalised estimating equation; iCCM, integrated community case management; QIC, quasi-likelihood under the independence criterion; RDT, rapid diagnostic test; VHW, village health worker.
