  • * Cochran-Mantel-Haenszel summary OR = 16.0 (1.3–200.8;P = .01) when “possible” cases are excluded; summary OR = 5.3 (1.3–21.4; P = .01) when “possible” cases are grouped with definite cases.

  • Cochran-Mantel-Haenszel summary OR = 3.6 (1.2–11.0;P = .02) for presence of neurologic abnormality.

    Data are number of infants (percent of column in parenthesis).
