The issue of generalisability to other settings or countries was not addressed and no appropriate comparisons were made with other studies. The results were not presented selectively.
Note by CRD Research Fellow:Correspondence with the authors indicates that, subsequent to this study, a book (Idiopathic Anaphylaxis, edited by Patterson R, (1997), Oceanside Publications Inc, Providence, Rhode Island) has been published which updates the findings of the present study. The reader is referred to this source for further details.
