Input: Twenty-three randomised controlled trials were identified. A total of 3872 and 2915 participants in the intervention and in the control group, respectively, were analysed. The weighted mean difference (WMD) for the level of glycosylated haemoglobin was -0.08 (95% confidence interval (CI) -0.12 to -0.04) in favour of the long acting insulin arm. The WMD between the groups in fasting plasma and blood glucose levels was -0.63 (95% CI -0.86 to -0.40) and -0.86 (95% CI -1.00 to -0.72) in favour of the long acting insulins. The odds ratio for a patient on long acting insulin to develop any type of hypoglycaemia was 0.93 (95% CI 0.8 to 1.08) compared to that of a patient on intermediate acting insulins. The OR for severe hypoglycaemic episodes was 0.73 (95% CI 0.61 to 0.87), and 0.70 (95% CI of 0.63 to 0.79) for nocturnal episodes. The WMD between the long and intermediate insulin groups for hypoglycaemic events per 100 patient follow up days was -0.77 (95% CI -0.89 to -0.65), -0.0 (95% CI -0.02 to 0.02) and -0.40 (95% CI -0.45 to -0.34) for overall, severe, and nocturnal hypoglycaemic episodes. Weight gain was more prominent in the control group. No difference was noted in the quantity or quality of severe adverse events or deaths. Long acting insulin preparations seem to exert a beneficial effect on nocturnal glucose levels. Their effect on the overall diabetes control is clinically unremarkable. Their use as a basal insulin regimen for type 1 diabetes mellitus warrants further substantiation.
Output:

Twenty-three studies fulfilled our inclusion criteria with a total of 3872 and 2915 participants in the intervention and in the control group, respectively. The methodological quality of all the studies was rated intermediate to low. Trials duration was no longer than one year. The level of glycosylated haemoglobin, a marker of diabetes control, was lower in the long acting insulin group, but the observed difference was of doubtful clinical significance. Longer acting insulins were superior mostly in their nocturnal effect, which resulted in a lower level of fasting glucose levels and fewer episodes of nocturnal hypoglycaemia. No data on long term complications were available.  The currently available data can not substantiate conclusions on the benefits and risks of long acting insulins, and long-term data are of need.
