Relative risk and risk ratios

Public Health professionals and epidemiologists often do risk calculations. These might include risk ratios, absolute risk, relative risk and risk differences. In this video, Dr Greg Martin teaches how to understand and calculate risk. These techniques can be used in epidemiological research to inform public health policy.

I am doing my PhD in Epidemiology, currently studying for my qualifying exams and I can say these videos are SO informative and help break down concepts I learned years ago in such a fun way. Thank you for your hard work and amazing knowledge and communication abilities Dr. Greg!

[@ThEKeeYs]

[@genifromalamp7]

Your videos made all the different "tests" make sense by giving me a great 30,000' view, and then sorting them visually. All the visuals REALLY help!! I'm taking a M.S. in Global Health online and your lectures are a fabulous adjunct to what I am learning. Soooooo helpful! Thank you!!

Hello Dr. Martin At first, I really wanna thank you for this very easy explain way for the subjects in general and this one in particular. I have a question? How can in know the last updates in a field (any field) For me, Epidemiology? Thank you for answer J.A from Iraq

[@AWhite_]

You are great budyy

[@gregmartin]

Thank you!

[@zahranilukman5522]

Is there a different between relative risk and risk ratio

[@mohammadanisuzzaman7536]

Fantastic lecture, Dr. Greg. I am afraid, there is a typo in the infographic. In the infographic, it is shown for the non-smokers is, 53+798=842. this would be, 53+789 = 842. thanks.

[@shamusenright5387]

I noticed that too after putting the numbers into a spreadsheet.

[@janaemara2373]

Something is wrong with the data you gave for the smoking during pregnancy study. 53 + 937 does not equal 842 sir

[@user-sk2te4co4s]

I LOVE IRLAND

[@ta3iyoyo742]

[@kathytoms1008]

I have big background in epidemiology. But in french

[@claudiamariebermudez6727]

😃

[@matchandmonolids]

Just wanted to let you know that there is a miscalculation- the number should be 851 not 842 :)
