Abbreviation: CAD = coronary artery disease; CVD = cardiovascular disease; HF = heart failure
Values are the percentage (95% CI) for all variables, with an exception of ‘Years since diagnosed with CVD after cancer”, which is presented using the mean (95% CI). All values are estimated after accounting for the complex sampling design of the NHANES.
a P-value is for the between-group differences estimated from a linear regression model for a continuous variable and Rao-Scott x2 test of independence for a categorical variable.
b Cancer survivors who already had pre-existing cardiovascular diseases before diagnosed with cancer.
c Cancer survivors who acquired the cardiovascular diseases after diagnosed with any cancer.
d The time elapsed until they were first diagnosed with cardiovascular diseases after they were diagnosed with any cancer. When multiple CVDs were reported, the CVD diagnosed first was used to calculate average years.
