 Median clinical screening scores corresponding to samples taken during episodes of respiratory tract infection (RTI) in hematopoietic stem cell transplant recipients on the hematology ward, stratified for grade of RTI, and virus detection (n=136)

	Clinical screen score
	All samples	Virus‐positive RTI samples	Virus‐negative RTI samples	P *
All episodes RTI	2.0 (1.0, 2.0)
URTI	1.0 (1.0, 2.0)			0.003
LRTI	2.0 (1.0, 2.0)
U&LRTI	2.0 (0, 2.0)
All episodes RTI		2.0 (1.0, 2.0)	1.0 (0, 2.0)	0.02
URTI		2.0 (1.0, 2.0)	1.0 (0.75, 2.0)	0.7
LRTI		2.0 (1.0, 2.0)	2.0 (1.0, 2.0)	0.9
U&LRTI		2.0 (1.0, 2.0)	0.0 (0.0, 1.5)	0.2

^* Test of significance is the Wilcoxon signed rank test.

URTI, upper respiratory tract infection; LRTI, lower respiratory tract infection; U&LRTI, upper and lower respiratory tract infection.
