Relative Risk vs. Odds ratio

Odds ratio and relative risk

[KristinHlebowitsh]

I'm a US medical student studying for my boards, and found this explanation extremely helpful. Clear and to the point -- plus I love Prezi! Thank you for creating this.

Excellent! The best clip I have seen on this topic.

Excellent video. Especially good on why you can only calculate odds ratios in case-control studies.

Learning about odds ratio and risk ratio in my Evidence Based Practices class, and this is very useful information!

[drnetrikamadenlimbu]

I really admire illustration using a large diagram with scoops in and out, it really helped understanding the topic.
many thanks to you good sir!

I have a question: in a case-control study, does the matched control group need to have the same or similar number of elements as the test (with tennis elbow in this case)? Thanks!

Hello there, thank you for the video. Can y expain where you got 1.96 from? And then do you multiple 0.857 +/- 1.96 by 0.306? Also can you show calculation of 0.257 and 1.458? Many thanks for your help.

hi excelent video but I just have a doubt. When you calculated confidence intervals how did you get the" log (odds ratio)"? if you can explain that would be very useful.

[PUTHENTHOPE]

Very informative video and thank you. One major point about the required sample size was missing. Could you explain the required minimum sample size that derives from the population of size 505 for this study at 80% power (alpha = .05)?

[m.c.degroffdavis]

Could you give a quick tutor on converting between log and ln on a calculator (app)?
