Fig. 7. This figure shows a series of drop-down lists that require an individual to select “coronary artery disease” within the cardiovascular section. Within the coronary artery disease (CAD) field, there are four subfields: stability, angina class, treatment, and other. Within the angina class, third level is a selection list of 1–4 with descriptions (0 indicates asymptomatic; 1, symptoms with strenuous activity; 2, moderate activity; 3, 1 flight or 2 blocks; 4, any activity or rest). This series of sections, fields, and subfields (all with pick lists) allows the provider to complete a relational database describing the patient's comorbidities, which are all questionable.
