aP-value uses Fisher’s exact test to assess between-group differences in proportion of participants who used a patient portal feature at least once during 9-month follow-up period.
bBaseline refers to registration for the patient portal at the time of study enrollment; 9 months refers to patient portal activities at 40-weeks post-enrollment.
cUse of patient portal at 9 months is limited to participants who were registered for the patient portal.
