Corrigendum to: “Does high-dose gestational folic acid increase the risk for autism? The birth order hypothesis” (Medical Hypotheses (2019) 132, (S0306987719307388), (10.1016/j.mehy.2019.109350))

The authors regret and wish to correct small numerical errors that occurred in our recent paper in Medical Hypotheses (“Does high dose gestational folic acid increase the risk of autism? The Birth Order Hypothesis”). (doi: https://doi.org/10.1016/j.mehy.2019.109350.) In the second paragraph of “evaluation of hypothesis”, the number of children should have been 480,526 and not 504,028. This error stemmed from a change in the numbers appearing in reference 18 of our paper, which was In Press at that time. In the Background section, the very high folate levels in Raghhavan study (reference 11) should be >60.3nmol/L, and not <60.3, as printed. The authors would like to apologise for any inconvenience caused.
