The bibliographies of the retrieved articles and Exeter University departmental files were hand searched and all controlled trials of homoeopathy in eczema were considered.
Professor Edzard found that out of the 96 hits produced by the searches, only three trials met the criteria, of which two were non-randomised and one an RCT. All three trials had methodological limitations – similar design, non-randomisation, insufficient detail about treatments, being open to selection, and other biases.
The results of the only RCT did not find that individualised homoeopathic treatment is superior to placebo and enrolled patient numbers were small (only 14 out of 24 patients completed the study).
