Evidence predicts <30% outcomes.Building usefully complex models of health & careneeds a much larger scale of research, ‘in the wild’.

Improved liver function (pooled) = 0.15 (se=0.009), p<1x10-59
Similar effect alone or with other drugs {G = 0.12; G+M = 0.16; G+S = 0.16; G+S+M = 0.15G = glitazone, M = metformin, S = sulponylurea}
First glitazone Rx
Mean log(ALT) beforeMean log(ALT) after
Fitted trends do not join evidence of glitazone effect on ALT
Liver Function vs. Glitazones
From M. Sperrin
Trends in liver function among patients with type 2 diabetes:messy real-world data; effect consistent with best evidence.
