Glycemic trajectory after face-to-face diabetes self-management education: a dose–response meta-analysis
Authors' conclusion
Conventional face-to-face DSME programs produce substantial short-term glycemic improvement, but benefits diminish over time and this was unrelated to initial program intensity.
Study context
- Population
- Adults with T2D receiving face-to-face Diabetes Self-Management Education (DSME), reporting pre- and post-intervention HbA1c; randomized, quasi-experimental and observational studies (intervention arms); MEDLINE, Embase, CINAHL to February 15, 2025103 studies
- Outcome
- HbA1c trajectory over time after DSME
Methodological detailssingle-group pre-post cohorts, REMR-based meta-regression with restricted cubic splines, Risk of bias assessed with NIH Before-After Studies tool, Data beyond one year were sparse
- Single-group pre-post cohorts
- REMR-based meta-regression with restricted cubic splines

Pooled result
As reported in the abstract
HbA1c change over time
Rapid HbA1c reduction within 30 weeks
≈1.3%
Further pooled results
Sensitivity analyses across restricted baseline HbA1c ranges
- Similar trajectories; regression to the mean did not fully explain the findings
Modification by program intensity
- Diminishing benefit over time unrelated to initial program intensity
