Group-based education excluding patients on insulin therapy results in greater reductions in HbA1c compared to interventions including patients on insulin therapy.
If you are on insulin, group education still helps, but the HbA1c reduction might be smaller than for those not on insulin. This may be due to the complexity of balancing insulin with lifestyle changes.
StrongQualifiesHIGH confidence
subgroup analysis of studies with regards to insulin therapy resulted in a significant subgroup difference (P < 0.00001), with interventions that excluded participants on insulin therapy resulting in greater reductions in HbA1c
Why this rating
Based on subgroup analysis of the same high-quality meta-analysis.
