Cross-country comparison to track campaign’s effect on Daily active devices The Poisson GLMM (AIC = 9613.3, logLik = −4792.7) indicated a significant immediate increase in daily active devices (DADs) in Cameroon following the campaign (β = 3.133, SE = 0.111, p < 0.001), with a marginally non-significant negative post-intervention slope change (β = −0.001, SE = 0.001, p = 0.063).
