Structured population data were available for 7 of 7 supporting studies. Diabetes type was heterogeneous: 5 studies with type 2 diabetes, 1 studies with type 1 diabetes. 5 studies described adult participants.

3 supporting studies do not have a displayable topic-matched quantitative effect.

Evidence uses heterogeneous comparison contexts: active_comparator, baseline_within_group, other, usual_care.
