After publication, it was noted by the authors that the dataset used for the analyses of occupational exposures in this study accidentally used incomplete occupational histories collected for 94 control fathers and 104 control mothers recruited in 2006, and these control parents were all treated as unexposed to occupational pesticides.
Results in Tables 1–3 and Supplemental Tables 1 and 2 (and the first three rows of Supplemental Table 3) of our published paper were unaffected by this error as they concerned household, rather than occupational pesticide exposure. The conclusions regarding the association with household exposure to professional pest control treatments are consequently unchanged.

Exposed in the year before pregnancy
Our original results for paternal occupational pesticide exposures were imprecise, and we concluded that these results were less clear than for household exposure but suggestive of a positive association. The revised ORs for paternal occupational exposure to pesticides are attenuated and offer little or no evidence of an increased risk. Our imputation analysis (Supplemental Table 3) still shows that these results were unlikely to be affected by bias due to missing job histories.
The sentence in the abstract concerning fathers’ occupational exposure should now read
“The OR for paternal occupational exposure in the year before the child’s conception was 1.11 (95 % CI: 0.55, 2.23).” There were still too few occupationally exposed mothers to analyse (2 cases/16 controls).
