  • *Error codes cross-reference to the observation recording forms shown in online supplementary file 2 and online supplementary file 3, table 4.

  • †Other IMG-related errors consisted of participants who were not confident to finish the simulation without assistance from a colleague and composite errors where a participant gave the dose as a short injection, so it was both undiluted and administered too quickly.
