I noticed that. But the conclusions were correct: unless you are a member of FLCC you don't view figures with 95% CI including 1.0 as definite enough to be proper conclusions.
They could have said: the results for metformin show a strong positive effect which is close to being statistically significant (CI=0.2 - 1.11). This motivates further studies of metformin.
