Good, but limited as definitions of the risk factors are not available (liver dysfunction is not a "yes" for just any degree of liver dysfunction. In addition, it would be VERY useful if the risk score gave a description of what it means ( i.e. Score of 4 indicates x% chance of major bleed per year etc...) These are easy updates and for the price of app should be included.
