  1. *Categories for socio-economic status (SES) combine highest education attained and/or household income range. **Total calories = ln(total calories). Case-control distributions (= N) for quartiles of nutrient consumption are provided in supplemental table 1 [see Additional file 1]. 1Also adjusted for study series. 2Quartile cutpoints were calculated from series- and gender-specific nutrient intake distributions among controls. 3CI = Confidence interval. 4 p-value for chi-square test for trend. 5 alpha- and beta-Carotene. Note: Boxed values are statistically significant odds ratios (with corresponding 95% confidence intervals that exclude 1.00) or tests for trend.
