Table entries are mean values (SD) for continuous variables or proportions for categorical variables.
Measured using the 51-item Potential for Benefit Scale (PBS); categories reflect lowest quartile (low), middle 50% (moderate) and highest quartile (high).
p-value computed from one-way analysis of variance for continuous variables and chi-squared test for categorical variables
Patients with a history of coronary heart disease (CHD) noted in the medical record.
Patients with no history of CHD noted in the medical record.
Data on medication regimen intensity were abstracted from medical records.
