Sample-weighted change in urinary methylated arsenic species [nmol/L per kg body weight] attributable to consuming each food group at the 90th percentile amount estimated from NHANES 2003–2010 data.

*: food group significantly associated with urinary arsenic species in regression models reported in Tables 3a and 3b.—: food group data insufficient to estimate sample-weighted percentile consumption.NA: rice beverage/milk was only evaluated in adults 20–84 years because no NHANES participants Sample-weighted change in urinary methylated arsenic species [nmol/L per kg body weight] attributable to consuming each food group at the 90th percentile amount estimated from NHANES 2003–2010 data.

*：回归模型中与尿液砷形态显著相关的食物组别，相关结果详见表3a与表3b。
—：该食物组别数据不足，无法估算加权样本的消费百分位数。
NA：米饮料/乳仅在20~84岁成年人中开展评估，原因是NHANES未纳入其他年龄段的参与者。
基于2003-2010年NHANES数据估算得出，当各食物组别摄入量处于第90百分位数时，由此引发的尿液甲基化砷形态加权变化量单位为纳摩尔每升·每千克体重。
