The original version of this article, published on 07 January 2019, unfortunately contained a mistake. The following correction has therefore been made in the original:

In section “Factors affecting improvements in the diagnostic performances of the residents during training,” the first sentence was worded incorrectly. The correct wording is as follows: “Of the 61 residents included, 40 (65.6%) showed significant improvement in AUC, and the remaining 21 (34.4%) did not show changes after training (Table 4).”
