Excludes hospitalizations linked to a primary SPRINT outcome. These primary SPRINT outcome events include the first occurrence of myocardial infarction, stroke, heart failure, or non-MI acute coronary syndrome.
P-values computed using the Tweedie distribution; analyses were repeated with the gamma distribution which yielded similar results.
There was no evidence of a difference in secondary event hospitalization rates after adjusting for age, gender, ethnicity, previous CKD, previous CVD, and systolic blood pressure (p=0.27).
Formal test of interaction with the treatment arm p-value: Previous CKD p=0.058; Age p=0.157; Sex p=0.294; Race p=0.219; Previous CV disease p=0.469; Systolic BP p=0.564.
