TruePositive undertakes observational research, statistical analysis and research training. Engagements are scoped and delivered by the same person, without an intermediate delivery team. The practical consequence is a limit on how many parallel workstreams can be supported at one time, and a corresponding depth on those that are. Where additional capacity is required, the work is carried out alongside a client's internal team, or as a named specialist under a contract research organisation's or consultancy's contract.
Klaus Kaae Andersen
Founder and principal consultant
Klaus Kaae Andersen holds a PhD in statistics from the Technical University of Denmark, where he taught for a decade and was named Teacher of the Year. He led the unit for Statistics and Pharmacoepidemiology at the Danish Cancer Society Research Center for nine years, with a group of fourteen researchers, and was subsequently Medical Evidence Scientific Lead at AstraZeneca Nordics. In 2022 he co-founded the biostatistical consultancy Omicron, where he was Director of Statistics until its acquisition in 2024, and held the same role at the contract research organisation Sanos until 2026.
His research comprises 164 peer-reviewed papers, including in Nature, JAMA, The Lancet Oncology and the Journal of the National Cancer Institute, with an h-index of 58. The substantive work concerns cancer epidemiology and survivorship, pharmacoepidemiology and confounding by indication, and stroke; the methodological work concerns competing risks, matched cohort survival estimation and register linkage. Most of it is conducted in Danish and Nordic national registers.
