Fig. 3From: Reduced neurobehavioral functioning in agricultural workers and rural inhabitants exposed to pesticides in northern Chile and its association with blood biomarkers inhibitionDistribution of the seasonal changes of blood biomarkers (AChE, BChE and APEH) in exposure groups (EE and OE). Each point represents the ratio between biomarker activity during spray and pre-spray for a given individual. Values above 1 suggest increase of the biomarker activity at spray season, while values below 1 implies decrease of the activity. The inner legends show for each group the results for a one-sample t-test (Ho: true mean = 1) for the activity value of each biomarker. The red line along 1 represents no temporal changeBack to article page
