Data on seasonality of deaths due to asthma were omitted from paper but editorial’s author did not know

Editor–Readers of Ann J Woolcock’s editorial about our paper may have wondered at her comments on the seasonality of deaths due to asthma¹ although data on this were not presented in our paper.² This was because we had been asked to remove these results to shorten the paper and she had not been told. However, we wish to present them here. The dataset was the same as that referred to in our paper. Briefly, all deaths due to asthma (International Classification of Diseases code 493) in England and Wales from 1 January 1983 to 31 December 1995 were included. Deaths were divided into calendar months, an adjustment being made for the different lengths of the months. Age specific rates were calculated using the mid-period population (1988) and the age groups 0-4, 5-14, . . . [Full text of this article]
