Basic statistics of Set 1. Sex-aggregated and -differentiated data are given for age, CRN, and urinary arsenic of the five result modes detailed in Table 3: Uncorrected (UC), Conventional CRN-correction (CCRC), Sex-differentiated simple power functional CRN correction (S-PFCRC SD), Sex-aggregated (V-PFCRC SA) and Sex-differentiated variable power functional CRN correction (V-PFCRC SD)
