*Categories for socio-economic status (SES) combine highest education attained and/or household income range. Case-control distributions (= N) for quartiles of nutrient consumption are provided in supplemental table 1 [see 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.
