Rapid responses are electronic comments to the editor. They enable our users
to debate issues raised in articles published on bmj.com. A rapid response
is first posted online. If you need the URL (web address) of an individual
response, simply click on the response headline and copy the URL from the
browser window. A proportion of responses will, after editing, be published
online and in the print journal as letters, which are indexed in PubMed.
Rapid responses are not indexed in PubMed and they are not journal articles.
The BMJ reserves the right to remove responses which are being
wilfully misrepresented as published articles or when it is brought to our
attention that a response spreads misinformation.
From March 2022, the word limit for rapid responses will be 600 words not
including references and author details. We will no longer post responses
that exceed this limit.
The word limit for letters selected from posted responses remains 300 words.
I greatly enjoyed the paper by Stahl-Timmins and Appleby, who analyzed causes of death, reported by John Graunt (1620-1674) in his renowned pamphlet “Natural and Political Observations mentioned in a following index, and made upon the Bills of Mortality” (1662) [1]. I agree with their conclusions on the problems of accurate data reporting and consistent classification of deaths in ancient (and modern) documents.
Recently, some scholars have started to apply modern statistical and epidemiological methods in analyzing ancient mortality registers, for understanding the prevalence of some diseases in ancient populations. This kind of analysis - known as paleo-epidemiology - may provide important information on the diffusion of diseases in past-times. For example, a recent paleo-epidemiological analysis has evidenced a high number of uterine cancers in a Northern Italian city at the beginning of the nineteenth century, probably due to poor hygiene and sexual promiscuity [2].
In conclusion, I suggest to the authors of this paper that they continue and deepen their analysis, applying modern statistical methods. I believe that the identification of actual number of inhabitants in London in the seventeenth century is determinant for this kind of analysis.
