P value

P value in the rightmost column refers to the test of any difference between groups in the relation between KDPI and 1-yr eGFR.

Superscript letters indicate P<0.10 for pairwise comparisons in crude analysis, and P<0.05 in adjusted analysis as follows:

Standard vs Dual

Standard vs Single Sc<4

Standard vs Single Sc=4

Dual vs Single Sc<4

Dual vs Single Sc=4

Single Sc<4 vs Single Sc=4

KDPI, Kidney Donor Profile Index (see text); STANDARD, Standard Criteria Donor kidney transplant; DUAL, Dual kidney transplant; SINGLE Sc. <4, Single kidney transplant with PTDB yielding a score<4; SINGLE Sc. =4, Single kidney transplant with PTDB yielding a score=4; eGFR, estimated glomerular filtration rate; IQR denotes interquartile range, 95% CI denotes 95 percent confidence interval.
