the use of other diabetesmedication
(i.e. insulin, oral hypoglycaemic agents, or both) was similar
between groups in five trialsIn one study (Blevins
2007), use of diabetes medication was much higher in the placebo
group relative to the cinnamon group (91% vs. 77%, respectively).
Four trials (Khan 2010;Mang 2006; Suppapitiporn 2006;
Vanschoonbeek 2006) did not provide sufficient data to make
between-group comparisons of diabetes medication use.Without
this information, it is difficult to determine whether the findings
of these studies are affected by additional risk of bias.
