*p Value according to the McNemar test.
†Neurocognitive performance measured using the ‘Digit-Span Task’. Higher values reflect a better performance.
‡p Value according to paired t test.
§p Value according to the Stuart-Maxwell test.
¶Ib and II: High and moderately hazardous pesticides.
**The difference in average years of schooling between T1 and T2 exists because some people took literacy courses, thus adding study time.
IPM, integrated pest management.
