  1. * White non-Hispanic subjects as a percentage of all race-ethnicities enrolled in each study.
  2. † Percentages reflect grade available for serous, mucinous and endometrioid carcinomas and for which we applied the algorithm to reduce histologic misclassification (see Methods).
  3. ‡ All studies except GER used frequency matching.
  4. § Includes the epithelial histologic types: serous, mucinous, endometrioid, clear cell, mixed epithelial, transitional cell, squamous cell, and undifferentiated.
