Continuous Glucose Monitoring in Type 1 Diabetes, Type 2 Diabetes, and Diabetes During Pregnancy: A Systematic Review with Meta-Analysis of Randomized Controlled Trials.

Continuous glucose monitoring (real-time CGM [RT-CGM] and retrospective [professional] CGM [non-RT-CGM]) is an emerging tool to assess glucose levels and variability. We performed a meta-analysis of randomized controlled trials (RCTs) to assess the effect of RT/non-RT-CGM on type 1 (T1D), type 2 (T2D), and diabetes in pregnancy (DiP) compared with self-monitoring of blood glucose (BGM). We searched PubMed/EMBASE/Cochrane Central Register of Controlled Trials until October 2024.
