The fundamental requirements of a prediction model for adverse pregnancy outcomes in women with gestational diabetes

Criteria	Specifications
(1) Prognostic versus diagnostic prediction model	The aim is to predict future events (prognostic prediction model)
(2) Intended scope	To inform clinicians’ therapeutic decision-making and serve as a rational basis for the stratification of GDM care
(3) The target population to whom the prediction model applies	Pregnant women with GDM, per diagnostic criteria in clinical practice
(4) The outcome to be predicted	Pregnancy complications related to GDM affecting the mother (obstetrical or maternal) or the baby (fetal or neonatal)
(5) Timespan of prediction	Complications occurring during pregnancy or soon after birth
(6) Intended moment of using the model	At diagnosis of GDM, typically at 24 to 28 weeks gestation but may be earlier

Framework adapted from that originally proposed by Moons and colleagues to consider in framing a systematic review of prediction modelling studies.⁴⁸
