indicates the binary variable that distinguishes PWH from NHANES ( for PWH, for NHANES); PWH, patients with hemophilia; NHANES, subjects from the National Health and Nutrition Examination Survey of the general United States population; , regression coefficient for representing change in log SBP per unit increase of the selected covariate; CI, confidence interval; , square of the multiple correlation coefficient; BMI, body mass index; eGFR, estimated glomerular filtration rate; HCV, hepatitis C virus.
Cage, Cage2, log BMI, eGFR, log TotalCholesterol, smoking status, HCV, and race.
race interaction was significant and therefore ANCOVA cannot be performed.
