NS: not stated; p: prospective; r: retrospective; elective: nonemergency patient; BLS: basic life support; FPIS: first-pass insertion success; OPIS: overall-pass insertion success. If the success rate was 100%, it was assumed that the lower confidence interval (CI) was reached and that the next attempt would fail.
