p-values obtained using generalized estimating equation approach to compare groups accounting for repeated measures at individual subject level.
p-value comparing AR to control
p-value comparing ACR grades 1 and 2 to ACR grade 0
p-values comparing pAMR grades 1 and 2 to grade 0
p-values comparing severities of allograft dysfunction to no allograft dysfunction. Subjects may have more than 1 category of endpoints.
