β is the unstandardized regression coefficient. aUnivariate analysis (n = 202): percent methylation = α1 + β1 cadmium in blood/urine. bAdjusted analysis (n = 202): percent methylation = α1 + β1 cadmium in blood/urine + β2 × age + β3 × coca chewing. cAdjusted analysis (n = 201): percent methylation = α1 + β1 cadmium in blood/urine + β2 × age + β3 × coca chewing + β4 arsenic in urine. |
