Where they differ
From the rowsThe best-graded row, grade C, is a meta-analysis of 952 people (2026) and found an improvement.
The 5 rows that found an improvement were larger: a median of 120 people, against 10 people for the row that found no difference.
Only the 5 rows that found an improvement include pooled reviews of several trials (2 of 5); the row that found no difference is a single study.
Only the 5 rows that found an improvement name women and men in their population. Only the row that found no difference names children or teens in its population.
The best grade is C among the rows that found an improvement, and D among the row that found no difference.

Open-label trial · n 10 · 2014 · 10 children with type 1 diabetes
Amount varied by child · Two study phases
No difference in mean blood glucose excursion after meals or in hypoglycaemia between phases; more added fibre correlated with lower post-meal peaks (-0.86 lunch, -0.76 breakfast).
