Bibliography

A citation analysis of my 110 publications in OpenAlex, October 2026. OpenAlex citation counts are lower than Google Scholar's and closer to Clarivate's (Web of Science).

Reach. 3,239 works cite my publications (4,881 citations in all), and 65% of them have no author in common with me or any of my coauthors. A further 82,601 works cite those works.
Standing in the field. Of the 96 publications that OpenAlex ranks against works of the same field and year, 16 are in the most-cited 1% and 60 in the most-cited 10%. The median publication is cited about four times as often as comparable works (field-weighted citation impact 4.1).
Use. 65% of citing works draw on my publications for background, 15% use the Agincourt data or study site, and 12% use a method or software. Medicine accounts for 43% of citing works, and 48% have an author based in Africa.
Software. 429 publications use, evaluate or cite the openVA family of verbal autopsy software, 243 of them by running it. 160 of these cite none of my publications, so the software reaches users that citation counts miss.

Most-cited publications

The ten publications cited by the most works, with each one's field-weighted citation impact (FWCI: its citations relative to works of the same field, type and year; 1 = average).
