BP, blood pressure
a
Analysis of variance with repeated measures. Each variable was analyzed separately and no adjustment was made for multiple comparisons. Values not normally distributed were logarithmically transformed before analysis.
b
Donors versus controls P values test overall differences between donors and controls.
c
Visit P values test differences between the 4 visits.
d
Interaction P values test the interaction between donors versus controls and between visits.
