¹In total, there were 14 deliveries recorded as neonatal deaths without a code specifying the mode of delivery. ² Includes liveborn infants only. Before 01.01.2012, recorded SwissDRG and TARMED codes did not correspond to the codes we used to identify deliveries (example of codes which were recorded before 2012 but were not counted as deliveries: “O64A”, “O64B”, and “O61Z”). 104,098 pregnancies recorded from 80,320 women.
