Adjusted for matching variable age group

Unilateral retinoblastoma cases and cancer-free controls were matched on age group at time of interview (0–1, 2–3, 4–5, 6–7, 8–9, 10–11,12–13 and 14–15 years). One case missing vegetable intake was excluded.

Seven matched sets were dropped due to missing values for one of the adjustment variables.

Adjusted for mother’s race and education, mother smoked month before or during pregnancy, household income, prenatal vitamin use, and total calories per day.
