Multivariate analysis for grade II–IV acute GVHD

Variables		Number	HR	95% CI	P
HLA allele mismatch
0–2		20	1
3–5		20	2.14	.96–4.79	.06
Disease status at SCT
CR		22	1
Non‐CR		18	1.26	1.07–1.48	.006
AUC0–24 of MPA on day 21
≤30 μg h/mL		10	1
>30 μg h/mL		30	0.66	0.24–1.78	.41

AUC0‐24: 24‐hour area under the curve; CI: confidence interval; CR: complete remission; GVHD: graft‐vs‐host disease; HLA: human leucocyte antigen; HR: hazard ratio; MPA: mycophenolic acid; SCT: stem cell transplantation.
