Correction

An error appeared in the March 1998 issue of OB/GYN Clinical Alert. On page 86 in Dr. Berga's Special Feature, the fourth and fifth sentences in the first paragraph should have read: "There are at least two main types of estrogen receptors, ERa and ERb. There are also proteins known as promoters that assist receptors like ERa and ERb in gene activation." We regret any confusion this may have caused.
