Erratum to “World Allergy Organization (WAO) Diagnosis and Rationale for Action against Cow's Milk Allergy (DRACMA) Guidelines update – IV – A quality appraisal with the AGREE II instrument” [World Allergy Organ J 15(2) (February 2022) 100613]

The publisher regrets that the title of the WAO DRACMA Guidelines update article published in Volume 15, Issue 2, February 2022 of the World Allergy Organization Journal was incorrect with regard to the series order number. The published title of the article incorrectly identified the series order number as article VI. The correct number is IV. Therefore, the correct title is: “World Allergy Organization (WAO) Diagnosis and Rationale for Action against Cow's Milk Allergy (DRACMA) Guidelines update – IV – A quality appraisal with the AGREE II instrument.”
