Time-to-biopsy-completion by technique for each tested nodule. This figure summarizes the time-to-biopsy-completion in seconds for each resident for all trials for a given nodule using both long-axis and short-axis techniques. Out of the 14 subjects, 8 eventually reached staff-level proficiency on at least one attempt. In these 8 subjects, the mean trials required to reach staff-level proficiency was 3.5
