Sixty women were allocated before conception to take 4 mg of folic acid a day before and during early pregnancy and 44 complied with these instructions. Fifty-one women were allocated to placebo treatment. There were no recurrences among the compliant mothers but two among the non-compliers and four among the women in the placebo group. Thus there were no recurrences among those who received supplementation and six among those who did not; this difference is significant (p = 0.04). It is concluded that folic acid supplementation might be a cheap, safe, and effective method of primary prevention of neural-tube defects but that this must be confirmed in a large, multicentre trial.

Específicamente se habla de este tipo de tormenta cuando la velocidad promedio del viento, durante un minuto, alcanza cifras dentro del rango de los 63 a los 118 km/h. Como es posible de ver en los noticiarios y a lo largo de la historia, estas tormentas siempre son llamadas de cierta forma, la que guarda relación con el orden de aparición en el año y en términos del alfabeto. Esto de acuerdo a la relación determinada para todo el año por el Comité de Huracanes de la Asociación Regional.
