Selected publications

Thirty-two papers from a record of roughly 270. Every entry links to its PubMed record.

Chosen to show the range rather than the citation count: the randomised trials that carried the programme, the laboratory and imaging work underneath them, the systematic reviews that decided what was worth trialling, the economic evaluations, and the early first-author series in which everything was measured by hand. The complete list is on PubMed and Google Scholar.
