Single P-values apply to both UC and LL; when the two sites differ, values are presented as UC/LL and are in bold. NS, P > 0.05; NA, not used as a covariate. Of these variables, all are presented in the figures. Trend P-values from contrast analysis at UC and LL, respectively. Directionality is observed from the figures.
