For each digest, results are given from three different analyses: the effect of subject was tested in a model with subject as the only independent variable and the effect of time was tested in a model with time as the only independent variable. Surface and axial location (continuous) were tested together in the same model, with permutation tests restricted within subject in a type III anova. Digests of microbial communities from urinary catheters from 5 males and 3 females catheterized in a level 1 trauma center for 1 to 16 days.
*** is p <0.001, *p <0.05 and †p <0.10.
