The FreeStyle Libre systems* have been studied in two landmark randomised controlled trials (RCTs) which demonstrated improvements in diabetes outcomes for both Type 1 and Type 2 patients with diabetes, those are:

1- Bolinder J,et al. Novel glucose-sensing technology and hypoglycaemia in type 1 diabetes a multicentre, non-masked, randomized controlled trial. The Lancet 2016: https://pubmed.ncbi.nlm.nih.gov/27634581/
2- Haak T, Hanaire H, Aijan R et al. Flash glucose-sensing technology as a replacement for blood glucose monitoring for the management of insulin-treated type 2 diabetes: a multicentre, open-label radomised controlled trial. Diabetes Ther. 2016: https://pubmed.ncbi.nlm.nih.gov/28000140/

Both studies data collected with the FreeStyle Libre system and is applicable to the FreeStyle Libre 2 system based on technological similarities.
