In contrast, many PAH-related exposures were inversely associated with p53 mutation-positive cancer (which primarily comprised missense mutations, but also included silent, nonsense, and frame-shift mutations), and nearly all effect estimates for p53 mutation-positive cancer for a given exposure were lower than the corresponding effect estimate for p53 mutation-negative cancer (Table 2).
