EpiStats

So you want to change a patient’s current therapy because a new medication has a decreased risk of a particular side effect. That sounds reasonable, but have you taken other issues into consideration (e.g., efficacy, other adverse reactions, cost, etc.)? And how about the number needed to treat? Do you know how many patients would need to receive the new therapy as opposed to the old one before one patient less experiences the side effect? Determining the number needed to treat can be useful in clinical practice when analyzing the risk versus benefit between two therapies.
EpiStats provides a quick way to calculate up to twenty-five different biostatistics in epidemiology. All of the most important equations are here – from absolute risk reduction to specificity. Our calculator features a punnet square with highlighted boxes so that you know exactly what information is necessary in order to make the calculation. And if you’re not sure what goes into each box, then there is a little info button to help you out.

If you desire a better understanding of each equation, take a look at our flashcards and question bank. The flashcards aid in the memorization of important concepts, while the Board Review tests your ability to apply those concepts. You can also check out our EpiStats channel on youtube for a growing list of lectures. Learning how to solve these questions can help you feel prepared and relieve you of some stress come exam day. Personally, being able to quickly tackle similar questions on the USMLE allowed me to save a couple extra minutes, and it gave me a little bit extra of confidence too. So if you are up for the challenge, come try out our qbank!
