Groups 2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.

|---|---|---|---|---|---|---|
| Group 1 | Cardiovascular Disorders Digital Intervention Arm (CVD-I) | Individuals with cardiovascular disease who receive a targeted digital intervention aimed at increasing influenza vaccination~Targeted digital intervention: Messages that provide informational content on the influenza vaccine (sourced from the Centers for Disease Control and Prevention and the American Heart Association), specific information about influenza and cardiovascular disorders, and behavioral prompts (e.g., reminders) surrounding influenza vaccination behaviors. | 3,418 | 5,575 | OG000 | ClinicalTrials.gov |
| Group 2 | Cardiovascular Disorders Without Digital Intervention Arm | Individuals with cardiovascular disease who receive no intervention | 3,355 | 5,662 | OG001 | ClinicalTrials.gov |
