	Frequency	Percent
Overall: gut ± liver GVHD	1580/2500	63
Gut + liver GVHD	200/2500	8
Gut GVHD, no liver GVHD	1354/2500	54
Liver GVHD, no gut GVHD	26/2500	1
Skin GVHD present	22/2500	0.88

Patients undergoing first allogeneic transplants at the Fred Hutchinson Cancer Research Center and Seattle Cancer Care Alliance from July 1, 2003, through December 31, 2014 (G.B.M., unpublished observations).
