Summarized definitions of post-transplant hypertension from studies specifically examining the prevalence of post-transplant hypertension.

References	Incidence or prevalence	Definition	Study design	n	Mean time since transplantation (range)
Budde et al. (16)	Incidence 77.3% [81.6% persistent HTN (HTN both pre- and post-transplantation) and 18.4% post-transplant HTN (normotension during pre-transplantation but HTN post-transplantation)]	>150/90 or using antihypertensive medications except the single use of diuretics	A single-center cross-sectional study of patients with stable graft function (>3 months) Mean of ≥5 consecutive BP records Sphygmomanometer in the sitting position	409 patients (64.5% had pre-KTx HTN and 35.5% had pre-KTx normotension) Mean age 47 ± 1 (19–68) years	45 ± 2 months (3–204)
Malek-Hosseini et al. (17)	Incidence 60% [68% persistent HTN (HTN both pre- and post-transplantation) and 32% post-transplant HTN (normotension during pre-transplantation but HTN post-transplantation)]	145/95 or required antihypertensive medication	A single-center study	84 patients (67.9% had pre-KTx HTN and 32.1% had pre-KTx normotension) Mean age at transplantation was 33.5 ± 11.3 years (range 11–58)	34 ± 22.6 months (3–93)
