Acute rejection and lymphocytic bronchiolitis after community acquired respiratory virus (CARV) infection.

Pathologic Grading*	Post-CARV Infection (n=45)	Non-CARV Reference Group (n=526)	p value	RV Subgroup (n=28)	Non-RV Subgroup (n=17)	p value
A1-A4	4 (8.9)	69 (13.1)	0.64	2 (7.1)	2 (11.8)	0.62
≥ A2	2 (4.4)	26 (4.9)	1.0	0 (0)	2 (11.8)	0.14

					Data presented as n(%)

RV = rhinovirus. “Non-RV” subgroup includes co-infections with rhinovirus and another CARV. “Non-CARV Reference Group” includes all biopsies taken from lung transplant recipients during the study period excluding those taken for post-CARV surveillance.
