Figure 1
Timing of questionnaires in the Ovarian Cancer Cohort Consortium, by study. See Table 1 for full study names corresponding to each abbreviation. Triangles indicate a questionnaire mailing or interview. Ovals indicate the study enrolment period. Solid arrow lines indicate studies that are still actively following participants (i.e., planning to send additional questionnaires or conduct additional interviews to collect updated exposure and/or disease information). Dotted arrow lines indicate studies that no longer actively follow participants but are passively collecting participant endpoints via linkage with cancer and death registries. The countries within the European Prospective Investigation into Cancer and Nutrition (EPIC) collect data at different time intervals; data are shown for the country within EPIC with the shortest interval between questionnaires.

Unsupervised hierarchical clustering of ovarian cancer subtypes by their associations with risk factors. Unsupervised hierarchical clustering of (A) the four major ovarian cancer histotypes and (B) four ovarian tumour aggressiveness categories (highly aggressive = time between diagnosis and death <1 year; very aggressive = death in 1 to <3 years; moderately aggressive = death in 3 to <5 years; less aggressive = lived ≥5 years). Unless otherwise noted, the categories used in the cluster analysis were ever versus never parous, ever versus never oral contraceptive use, ever versus never tubal ligation, ever versus never endometriosis, age at menarche >15 vs ≤11 years, age at menopause <40 versus 50 to 55 years, ever versus never menopausal hormone therapy use, ever versus never hysterectomy, family history of breast cancer (yes vs no), family history of ovarian cancer (yes vs no), body mass index >35 versus 20 to 25 kg/m2, height (per 5-cm increase), and ever versus never smoking. The colour scale shows the range of β-values for each exposure.
