Jayne Tierney, Senior Research Scientist

Jayne has been a Research Scientist at the Unit since it was formed in 1999, and prior to that, in the Cancer Trials Office in Cambridge. For more than 20 years, she has been responsible for designing and conducting systematic reviews and meta-analyses to rigorously re-evaluate the effectiveness of therapies; projects that have influenced practice guidelines and the treatment of patients worldwide.

She leads a small group that has published international, collaborative, individual participant data (IPD) reviews in bladder, cervix, lung, oesophagus, and soft-tissue cancer, and advised on projects in pregnancy and wound care. In addition, she has been involved in systematic reviews of aggregate data in stroke, HIV, and fertility medicine, as well as in cancer. New projects are underway to evaluate the effects of therapies for prostate cancer.

Jayne is also involved in methodological research to try to improve how systematic reviews and meta-analyses are conducted and analysed. Current interests include how to do timely and reliable aggregate data meta-analyses, and how best to evaluate treatment covariate interaction in meta-analysis. Jayne also provides advice and training on systematic review methods, and is Deputy Director of the London Hub for Trials Methodology Research.

Jayne has been involved in Cochrane since its beginnings, providing peer review for Cochrane Review Groups and workshops at annual meetings and colloquia. She is one of the co-convenors of the IPD Meta-analysis Methods Group.
