^a Adjusted model controlled for months in program, initial weight, and organization.

^b Attendance groups based on Diabetes Prevention and Recognition Program standards (8). High attendance — core sessions and maintenance; participants attended ≥9 sessions in the first 6 months and ≥3 sessions in the second 6 months. Moderate attendance —core sessions only; participants attended ≥9 sessions in the first 6 months but <3 sessions in the second 6 months. Low attendance — participants attended ≤8 sessions in the first 6 months, regardless of attendance in the second 6 months.
