Prevalence of epilepsy in a rural community of Guatemala (vol 37, pg 373, 1996)

A portion of the Materials and Methods section was inadvertently omitted from this article. As Dr. Mendizabal believes that this text is relevent to the article from a scientific standpoint, it is reproduced here. The text that follows should have appeared immediately after the Materials and Methods heading and before the subheading Active Epilepsy. The authors and the publisher apologize for the oversight.
