*Week following randomization
† Patients were considered reached by an automated phone call if a message was left or the call was answered
‡ Patients were considered reached by a text message if their phone number in the medical record was a cell phone. No further information was available about whether a patient received a text message
§ Six patients had missing outcomes for live-call reminders. Of these, five had evidence of a completed FIT. These patients were kept in the per-protocol analysis to avoid bias
