NS: not stated; p: prospective; r: retrospective; OOHCA: out-of-hospital cardiac arrest; emerg.: emergency/no cardiac arrest; FPIS: first-pass insertion success; OPIS: overall-pass insertion success; RN: registered nurses. If the success rate was 100%, it was assumed that the lower confidence interval (CI) was reached and that the next attempt would fail.
