The table compares the prevalence of selected diagnoses that are reported in Table 1 in the entire cohort and after removing patients who did not perform ABPM as a routine screening test or patients who were taking BP medications. The effect of removing subsets of patients was evaluated by chi-squared tests; results are expressed using the P value. All tests failed to show significant changes in both subanalyses. ABPM, ambulatory BP monitoring.
