  • * All studies frequency matched controls to cases, minimally on age and sex. Additional frequency matching factors included center (Latin America), ethnicity, and neighborhood (Los Angeles study).

  • Two response rates are reported because data were collected in two population-based case-control studies: the first from 1985 to 1989 among men and the second from 1990 to 1995 among men and women.
