Median (interquartile range) spread of allograft kidney function parameters stratified by the high donor-derived cellfree DNA group using a cutoff of 1%

Characteristics	Low Donor-Derived Cellfree DNA (<1%), n=249	High Donor-Derived Cellfree DNA (>1%), n=39
Donor-derived cfDNA	0.28 (0.15–0.47)	1.6 (1.2–2.5)
Serum creatinine, mg/dl	0.9 (0.6–1.2)	0.9 (0.7–1.6)
Percentage change in serum creatinine	0.0 (−4.5 to 10)	−1.3 (−2.1 to 7.7)
eGFR, ml/min per 1.73 m2	68 (57–87)	62 (44–76)
Percentage change in eGFR	0.0 (−9.1 to 5.3)	6.7 (−20 to 25)

cfDNA, cellfree DNA.
