Correlation components from bivariate variance components analysis of hookworm infection intensity. The phenotypic correlation coefficient between initial and reinfection hookworm burden, and the correlation component (r), proportion of phenotypic correlation explained by each component (%), and significance of each correlation component (P) compared to a model with that correlation constrained to 0
