Within the LIFECODES birth cohort, the authors found that they were reverse-coding sex so that any results presented on female fetuses are actually representative of results in male fetuses, and vice versa. This resulted in errors in the values reported for fetal sex in Table 1; “Male” should read “Female,” while “Female” should read “Male.” The data that follows on each line is unchanged.
The authors regret the error.
