A, Overall view rates of outpatient diagnostic tests showing view rates among only those with an active patient portal account (red bars; patients with inactive portal accounts excluded) and total including those without an active account (blue bars). The upper dashed line shows the overall average view rates of all tests for those with an active account. The lower dashed line shows the overall average view rate (including those with inactive portal accounts). B, View rates of outpatient diagnostic tests subdivided by gender and showing view rates among only those with an active patient portal account (patients with inactive portal accounts excluded). C, View rates of outpatient diagnostic tests among only those with an active patient portal account subdivided by age distribution (patients with inactive portal accounts excluded). Patients aged 12 to 17 years and 81 years and older had significantly lower view rates than other ages (P < .001).
