Following publication of the original article [1], the authors would like to remove the incorrect group difference for atopic dermatitis in the Abstract. The correct group difference of Δ-DLQI: − 1.4, p = 0.086 is neither clinically relevant nor statistically significant. The correct value is stated in the main text and discussed in the correct way.

The sentence currently reads:

The primary effectiveness outcomes after six months were statistically significant in favor of the HOM group for migraine or headache (Δ = difference between groups, days with headache: − 0.9, p = 0.042), asthma (Δ-AQLQ(S): + 0.4, p = 0.014), atopic dermatitis (Δ- DLQI: − 5.6, p ≤ 0.001) and depression (Δ-BDI-II: − 5.6, p ≤ 0.001).

The sentence should read:

The primary effectiveness outcomes after six months were statistically significant in favor of the HOM group for migraine or headache (Δ = difference between groups, days with headache: − 0.9, p = 0.042), asthma (Δ-AQLQ(S): + 0.4, p = 0.014) and depression (Δ-BDI-II: − 5.6, p ≤ 0.001).
