Progression (A–C) or recovery (D–F) of acute allograft glomerulopathy. In the progression group, acute allograft glomerulopathy occurs by Day 18 (A) and gradually progresses to chronic allograft glomerulopathy from Day 60 (B) to Day 100 (C). In the recovery group, acute allograft glomerulopathy also develops by Day 18 (D), however, this gradually recovers on Day 60 (E) to Day 100 (F), leaving mild segmental proliferative lesions.
