Written by Dr. Edward Pullen, MD Check out drpullen.com, a medical blog for the informed patient. The CDC has a large number of online calculators that they make available on their web site. They have made several of these available as what those of us in the blogosphere call widgets, or blocks of text that can be embedded in a web site to show up as the calculator itself. I took the time to browse through the CDC site and here are some of my favorite calculators that are available as widgets. Feel free to come back to use them whenever you like. I’ll also add a brief comment for each. It’s amazing what this IT world has developed. Enjoy.
