Study participant distribution. *One pregnancy and one diagnosis of diabetes were discovered by the local investigator of Diagest 3, though questionnaires for Diagest 3-GP had already been sent to these patients’ GPs. Neither of the GPs returned the questionnaires. The red arrow indicates 10 GPs who were contacted but did not reply; these GPs were reintegrated into the Diagest 3-GP study population. GP = general practitioner; V4 = final clinic visit (3 years after inclusion).
