Data are expressed as number of patients. Easy: successful insertion on first attempt with no need for adjustment, slightly difficult: successful insertion on first attempt with the need for at least one adjustment, obviously difficult: successful insertion on second attempt, and impossible: insertion not successful after two attempts.
