A systematic analysis of UK cancer research funding by gender of primary investigator

OBJECTIVES: To categorically describe cancer research funding in the UK by gender of primary investigator (PIs). DESIGN: Systematic analysis of all open-access data. METHODS: Data about public and philanthropic cancer research funding awarded to UK institutions between 2000 and 2013 were obtained from several sources. Fold differences were used to compare total investment, award number, mean and median award value between male and female PIs. Mann-Whitney U tests were performed to determine statistically significant associations between PI gender and median grant value. RESULTS: Of the studies included in our analysis, 2890 (69%) grants with a total value of £1.82 billion (78%) were awarded to male PIs compared with 1296 (31%) grants with a total value of £512 million (22%) awarded to female PIs. Male PIs received 1.3 times the median award value of their female counterparts (P<0.001). These apparent absolute and relative differences largely persisted regardless of subanalyses. CONCLUSIONS: We demonstrate substantial differences in cancer research investment awarded by gender. Female PIs clearly and consistently receive less funding than their male counterparts in terms of total investment, the number of funded awards, mean funding awarded and median funding awarded.
