Welcome to Wikipedia
Are you also from Yale? Anyway a couple of things


 * 1) The titles for some of your refs are incomplete for example there is no article called "Sex, Age,Cardiovascular Risk Factors, and coronary heart diease" but it is actually appears to be which bring me to the second issue
 * 2) We have a guideline called WP:MEDRS that outlines what one should use for refs on Wikipedia, simply review articles and major textbooks are preferred. Please bring this back to your class and if you have further question feel free to contact me. Cheers -- Doc James (talk · contribs · email) 03:57, 17 December 2011 (UTC)
