  1. Regressions adjusted for age and alcohol consumption. Exposure to pesticide: 0 = non exposed; 1 = exposed. Ethylated metabolites of OPs: 0 = non detectable; 1 = over limit of detection. Time of exposure to pesticides (continuous variable). β ± SEM: Coefficient of regression ± Standard error of the mean. Data with non parametric behavior were log-transformed in order to performed linear regression analyses. *Holm's test adjustment.
  2. +Analyses were performed after controlling for urine levels of methylated OP metabolites, respectively.
