Correction

Following publication of the original article [1], the authors reported that they had had mistakenly put the wrong IRB number in the last paragraph of the Methods section (as IRB NO.: IRB101–80 instead of IRB102–20 as given in the Ethics approval and consent to participate in Declarations). The corrected last paragraph on the Method section should read as follows:

“Ethical approval was obtained from the institutional review board at Buddhist Tzu Chi General Hospital (IRB102-20). Informed consent was received from all participating medical students.”

Furthermore, they found that the name of the first author (Shao-Yin Chu) was not listed in both sets of Author Comments (21 Nov 2017, 18 Dec 2017) in their paper’s Open Peer Review Reports (https://bmcmededuc.biomedcentral.com/articles/10.1186/s12909-017-1114-x/open-peer-review), where the correspondence author’s name (Chi-Wei Lin) was listed twice.
