Legend: SVB Spontaneous vaginal birth
Annotation: Total births indicate all births in Switzerland per year – independent of birth mode. The number of CS represents all CS in Switzerland per year. In non-medically indicated CS, only the defined DRG-groups O01F (2014–2016), O01G (2017) and O01H (2018) are included. Spontaneous vaginal birth displays the number of births classified by the DRG-group O60D (2014–2018)
