In a recent article, “A case-control study of pesticides and fetal death due to congenital anomalies,” by E.M. Bell, I. Hertz-Picciotto, J.J. Beaumont (Epidemiology 12:148–156, 2001) the categorization for pyrethroid pesticides was incorrect. The corrected pyrethroid category includes the following pesticides: permethrin, pyrethrin, cypermethrin, fenvalerate, and flucythrinate. The corrected odds ratios and 95% confidence intervals for the pyrethroid analyses in Tables 5 and 6 are presented here. The authors regret the error.
Further analysis using this revised categorization is discussed in a letter in this issue.
