From: Intracluster correlation coefficients and coefficients of variation for perinatal outcomes from five cluster-randomised controlled trials in low and middle-income countries: results and methodological implications

Figure 2

Simulated impact of number of live births per cluster on estimated coefficient of variation ( k ) for maternal and neonatal mortality. These simulations were run assuming that all birth outcomes were independent, i.e. the true coefficient of variation was set to zero. As the number of births per cluster increases, the estimated coefficient of variation falls closer to zero indicating that more births per cluster lead to greater reliability in estimates of the coefficient of variation. Throughout, the estimated coefficient of variation is higher for maternal mortality than for neonatal mortality.
