Mean FEV1/FVC ratios by categories of BMI and single year lifetime highest arsenic exposure categories in ever smokers.

Abbreviations: As, single year lifetime highest arsenic water concentration; BMI, body mass index; FEV1, forced expiratory volume in one second; FVC, forced vital capacity (FVC).

Names along x-axis correspond to categories of arsenic exposure and BMI. Low and high BMI constitutes a BMI below and above the 90th percentile of 33.9 kg/m2, respectively. Low and high arsenic constitutes a single year lifetime highest exposure below and ≥11 µg/L, respectively. All categories were mutually exclusive
