    Ginger for allergic rhinitis: no significant difference is not proof of equivalence

    An active-comparator trial found improvement with both ginger extract and loratadine. A nonsignificant group difference alone does not establish that the treatments are interchangeable.

    What the experiment compared

    Eighty people with allergic rhinitis were randomized to ginger extract or loratadine. Researchers assessed nasal symptoms, quality of life and nasal-airway measurements over six weeks. [1]

    Both groups improved on nasal symptom scores, without a significant difference between them. Some other measurements and reported side effects differed. [1]

    Interpretation and limits

    The authors declared no competing interests; funding was not established from the abstract. The retrieved report does not establish a prespecified equivalence margin, and there was no placebo group. The findings concern a specific extract and allergic rhinitis, not all allergies or emergency allergic reactions. [1]

    A hypothetical distinction

    Imagine a small comparison cannot distinguish two treatments statistically. That may reflect similarity or limited precision; it does not by itself prove they differ by less than a clinically acceptable amount.
