Letters to The Editor continue to be a vital part of The Journal's
interaction with its readers. This feature provides a forum for readers to
comment on, criticize, or present additional data regarding published
scientific articles, and it allows the authors of the articles to respond when
questions are raised by the letter writer. Occasionally, the reader who
browses the Letters to The Editor section will find letters that take him or
her back to an article that he or she might have missed.
