How To Calculate The Number Needed To Treat

The NNT is the number of patients you need to treat with the experimental therapy to prevent one additional bad outcome. This video will demonstrate how to calculate NNT

Amazingly helpful, exceptionally simple and straight forward. Love your work!

Thorough and clear explanation! Thank you so very much for helping me to tackle the hardest part of my journal club presentation. I have never fully understood this calculation, and your video cleared-up all confusion.

Man, You surely know how to teach. Congrats! Thanks from Brazil!

These videos are so helpful. I am really understanding EBM, thanks to these vids.

so  clear, so helpful examples, and  final analysis  all  best. please continue  on  more videos  on biostatistic  and epidemiology  as  these  are  real  bothering subjects in all  exams. thank  you!!

So is the absolute risk increase still CER - EER?? or is it now EER - CER? Thanks

[UABEBMcourse]

Doesn't really matter as it's the absolute difference between event rates. But to help you think about it better EER would be lower than CER to calculate a RRR and NNT

Weird how this was once of blur to me. Thank you!

Hi  sir, thank you so one query ... why did you mention that NNT for the duration of the study ...does that mean, the 9 person  need to be treated only for the duration authors specified in the study...please

[rajeevmisra]

With due respect, this is wrong, NNT as a rule is always rounded up. So, 100/11 is 9.09 and thus the answer should be 10. You need to treat just more than 9, which is 10.
