AFB1-lys: Covalent adduction of Aflatoxins B1 to lysine residues in serum albumin. CI: Confidence Interval. LSM: Least Square Means.
Estimates are dietary consumption of maize/tortilla in grams/day expressed as the range of consumption within each quintile.
Estimates in crude and adjusted models were calculated through linear regression analysis and represent LSM and 95% CI of levels of AFB1-lys adduct in pg/mg by each quintile of total maize/tortilla. Values of AFB1-lys levels were back transformed. P for linear trend <0.05 show the association of AFB1-lys across quintiles of consumption.
Adjusted model includes covariates for sex, education, income, residence and total calorie intake.
