Baseline Characteristics
For the primary analysis, one patient per phone number was included to preserve independence of observations since randomization occurred on the phone number level. If a phone number was associated with more than one enrolled patient, we prioritized the first patient enrolled if enrollment dates differed, GHP members if enrolled on the same day and GHP membership differed, or selected a patient randomly if all shared the same enrollment date and GHP membership status.
