"One-way ANOVAs showed no main effects of condition on diagnostic accuracy, F (1, 54) = 1.28, p = 0.263".

The authors admit that their sample was almost half as large as they had hoped and, thus, perhaps insufficiently powered to detect the effect they expected.

"Ninety-nine residents followed our invitation and came to the first study session, and 56 of them (39 female; age M = 29.05, SD = 2.85) completed both sessions."

Medical residents randomized to "the experimental condition [studied three] examples of the procedure that they would be asked to teach. ... Each example showed the reflection procedure [which[ requires the physician to first read a case and give an initial diagnosis. Subsequently, the physician goes back to the case and lists (1) findings that support the diagnosis, (2) findings that oppose the diagnosis, (3) findings that would have been expected if the diagnosis were true, but were absent. The physician then gives (4) an alternative diagnosis and follows the same analytical steps (1–4) for this alternative diagnosis, and for a third diagnosis."
