Y dependent variable, N number of individual birds in model, X independent variables in final model, CI 95% confidence interval, p p-value. Dependent variable “mallard cloaca virus titer” includes virus titers from cloacal swabs collected on the DPI each bird was sacrificed. Proximal includes the duodenum and jejunum. PC1 represents the principal component variable for the proximal villi enterocytes, brush border, and crypt enterocytes combined. BCS = Body Condition Score. Group and Sex were treated as factors in each model, and if present in final model, group T1 and females are represented in the intercept
