TABLE 3.

C/D ratios in patients with severe vs. no BKV infection.

BKV status	n	Time-to-maximum-copy-load in days (mean ± SD)	C/D-ratio (median [IQR])	Mann-Whitney test (p-value)
Severe BKV infection	32	168 ± 101	1.55 (1.19–2.08)	0.801
BKV negative	345	190 ± 36	1.46 (0.97–2.23)

Severe BKV infection was defined as a copy load exceeding 100,000 U/mL. BKV negative patients with available C/D ratios 6 months post-transplantation served as controls. BKV, BK virus; IQR, interquartile range; SD, standard deviation.
