From: Initiation and duration of folic acid supplementation in preventing congenital malformations
Predicted probability of congenital malformations by the initiation and duration of folic acid supplementation. The predicted probabilities of congenital malformations in women without folic acid supplementation were 2.35% and 2.37% in the initiation (A) and duration (B) analyses, respectively. The tolerable risk was 1.519% and 1.492% for the initiation and duration of folic acid supplementation, respectively
