In the published article, there was an error. The units of measurement for the Vaseline and IMQ cream were incorrectly listed as μg instead of mg.
A correction has been made to Methods and materials, Psoriasis induction and scoring of psoriasis area and severity index, paragraph 1. This sentence previously stated:
“The normal group applied Vaseline on exposed back skin (40 μg) and both ear skin (20 μg/ear) for 7 consecutive days. And the disease-induction groups were applied with 5% IMQ cream (Aldara cream, Dong-A S&T, Inc. Seoul, South Korea) on exposed back skin (40 μg) and both ears skin (20 μg/ear) from day 1 to day 7.”
The corrected sentence appears below:
“The normal group applied Vaseline on exposed back skin (40 mg) and both ear skin (20 mg/ear) for 7 consecutive days. And the disease-induction groups were applied with 5% IMQ cream (Aldara cream, Dong-A S&T, Inc. Seoul, South Korea) on exposed back skin (40 mg) and both ears skin (20 mg/ear) from day 1 to day 7.”
The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
