Gestational diabetes & diabetes in pregnancy
Impact of a modified screening approach during the COVID‐19 pandemic on the diagnosis and outcomes of gestational diabetes mellitus: A population‐level analysis of 90,518 pregnant women
Authors' conclusion
The COVID-19 epidemic had no impact on screening for GDM. Women who underwent modified screening, based on HbA1c/random plasma glucose, had lower rates of GDM cases.
