  • a In each cell, the direction and strength of the association is indicated, together with the number of studies that pointed to that direction out of the total that have adequately examined the particular association. Cancers for which a nonnutritional factor of overriding etiological importance has been identified, have not been included in the table (oral cavity, larynx, lung, and urinary bladder excluded because of the effects of smoking; hepatocellular carcinoma and cervix uteri excluded because of the effects of viral etiology; ovarian cancer excluded because of the effects of oral contraceptives and reproductive factors).

  • b NE, no evident association.
