Abstract

Parasites spread through shared environments, so observations from hosts sampled in the same environment are rarely independent. Ignoring shared environmental effects can lead to an underestimation of study outcome uncertainty and the potential to draw incorrect conclusions. Intraclass correlation coefficients help address this issue by quantifying cluster-level effects and adjusting sample sizes.
