Subject Characteristics.

Note. Clinical rotations begin in the third year of medical school, so “years of experience” begins in year 3. A fourth year student is designated one year of experience. Experts were asked how many years in practice they had (after schooling was completed), so six years were added to their responses: a physician with one year in clinical practice was assigned 7 years of experience. In the Training Subcategory column, “PGY1” refers to Post Graduate Year 1, M2 refers to Medical School Year 2, etc.
