Results for the sigmoid random effects model (Sigmoid RE) for the AvecNet trial, compared to a generalized linear mixed effects model from the original analysis [23] (GLMM)

	Sigmoid RE	GLMM [23]
IRR	0.83, $[0.70,1.00]$	0.88, $[0.77,0.99]$
$\widehat{\theta }$ (in km)	0.101, $[0.051,0.745]$	–

The results are reported in terms of the incidence rate ratio (IRR). The contamination range $\widehat{\theta }$ is only estimable for the sigmoid random effects model
