In this updated Cochrane systematic review, we identified 28 RCTs comparing intensive glycaemic control versus conventional glycaemic control in participants with T2D. A total of 18,717 participants randomised to intensive glycaemic control and 16,195 to conventional glycaemic control were included in the analyses. The trials were primarily conducted in Europe and Northern America. The mean duration of the intervention period varied from three days to 12.5 years. Only two trials were considered to have low risk of bias; we may, therefore, have evaluated RCTs with high risk of overestimating beneficial effects and underestimating harmful effects. - See more at: http://summaries.cochrane.org/CD008143/ENDOC_targeting-intensive-glycaemic-control-versus-targeting-conventional-glycaemic-control-for-people-with-type-2-diabetes-mellitus#sthash.u4uLS1sv.dpuf
