New Review Format for RTN:  In response to your suggestions, we are using larger print in this edition.  We are also taking our reviews of reference [REF] articles more in-depth.  We began more detailed reviews in July with one format and are trying out a slightly different one this month.  Please compare the review approach used in a July Reference Article with an August Reference Article. Then let us know which you prefer.  We want to help you make better use of your limited reading time. Thank you. R. Fields, MD
