1 November 2018	New citation required but conclusions have not changed	The overall conclusions have not changed. There are data from two new studies, which adds some data to one of the six comparisons: 'Continuous glucose monitoring (CGM) versus intermittent glucose monitoring'. There is now evidence to suggest that CGM may reduce hypertensive disorders of pregnancy, although the results were less clear for the single outcome of pre‐eclampsia. CGM may reduce neonatal hypoglycaemia.
1 November 2018	New search has been performed	Search updated and six studies were assessed for eligibility. Two studies have been included (Feig 2017; Voormolen 2018), two are ongoing (Link 2018; Logan 2011), one is an additional study report of an already included study (di Biase 1997), and one is an additional report of an already excluded study (Bartholomew 2011).
30 November 2016	New citation required but conclusions have not changed	One new trial added and the conclusions remain unchanged.
30 November 2016	New search has been performed	Search updated, seven trial reports identified. One new trial added for this update from ongoing studies (Dalfrà 2009). The review now includes 10 trials. 'Risk of bias' assessments for blinding have been updated to include assessments of both performance and detection bias. 'Summary of findings' tables have been incorporated.
