From iMedicalApps in 2016: “The evidence based medicine (EBM) components of the medical app are what really set MDCalc apart from its peers… The MDCalc app gives brief summaries of the critical studies concerning the medical calculator, links to the studies on PubMed as well as “pearls/pitfalls”, “next steps” and expert commentary from the authors of the calculators.” – iMedicalApps “MDCalc app, the best online medical calculator is now an app”
