  2. aNs may not sum to the total because of missing or unknown data; proportions (%) sum to 100% of observations where data was available and excludes missing/unknowns.
  3. bOther epithelial include mixed subtypes where serous or clear cell component does not reach the percentage noted, or where the histology was unknown (2 individuals were diagnosed by curettage).
