Thank you for the helpful video (from the University of Toronto)!
Dear Dory. Thank you for your kind explanation. English is not my native language, so it is very useful for me that you explain slowly and logically.
Glad you found it useful!
The best video I've seen in TH-cam for survival analysis. thank you very much
Thanks!
Hello Dory, you have explained Kaplan Meier survival in a very clear way. Thank you.
Thanks
It's a one of my favorite video I have seen. I am Korean Highschool Student and learned a lot from this video. Thank you for your kind teaching!!
My pleasure
OMG, thank you very much for this video. That saved me today! I was looking for a good explanation of this and it was hard to find. Thank you!
My pleasure!
I watch almost all your videos. Thank you so much.
My pleasure!
Merci beaucoup pour votre tuto , simple et efficace , le logiciel le plus simple à utiliser et intuitif
Excellent. I appreciate your kind effort.
Thank you for sharing this video. It's very much helpful for the survival analysis of my animal study.
Glad you found it useful. Plenty more to come
thank you for this winderful video.. was able to plot the survival plots very easily after following this video..
Happy to help!
Thank you so much Dory, very helpful video
My pleasure!
Muchas gracias por subirlo. La explicación es clara, objetiva y de mucha ayuda.
My pleasure!
Thank you very much for the video. It was very usefull for my research!
Glad you found it useful
This video helped me a lot, thank you so much! :)
My pleasure!
super clean and useful video, thank you.
Glad you found it useful
Nicely explained. Thank you so much
My pleasure
Thank you for lucid explaination
My pleasure!
Hello Dory, thanks a lot for the video. How can we show in the graph the number of subject at risk at each timepoint ? It's more informative. Many thanks for your reply
Muito obrigado! Thanks from Brazil!
My pleasure
The best tutorial. Short, perfectly paced, so that I can follow along. I wonder how do I calculate the survival of a single group with regard to primary patency (stent is patent), assisted primary patency (stenosis requiring angioplasty to keep to open), and secondary angioplasty (stent occluded but it was possible to open it using additional procedures). Usually, this is shown in a single graph. How do I plot limb survival in a single group and also comparing two groups ?
Glad it was helpful!
Thank you so much. Clear explanation..
Glad you enjoyed it
Thanks a lot for the video and explanation
You are welcome
Thanks for the video.
My pleasure
Thank you very much for the excellent video. Do you have a video for univariate and multivariate analysis for graphpad prism as well?
Think this is a great way to do good for the world,,, in this day and age, good deeds are not just volunteering to build an orphanage or a school..ets. good deeds could be volunteering your time to educate people for free! Awesome work keep going
Absolutely
Super clear as always. Might you do a video on pairwise analysis on multiple comparisons? I found the Graphpad help page on this quite hard to follow. Many thanks in advance!
Glad you found it useful. Plenty more tutorials to come
omg the music in the beginning sent me back to my childhood
:-)
very informative , thanks
My pleasure!
Thank you for the detailed video. Which version of prism did you use?
I always use the latest version
Found this useful
Glad to hear it
Nice work
My pleasure
Thank you so much!! // Muito obrigada!
My pleasure
Agradecida por este video. espero pueda hacer mas. saludos
Eh? Translation please?
@@DoryVideo Thankful for this video. I hope I can make more videos. regards
Thanks for that!
I am curious if you just enter the value 1 or 0 in the A column then how the program can understand to calculate the survival rate
Hey! How did you get the Hazard Ratio? I use Prism 8 & can't find it
Hi video is very much helpfull... After seeing this video I was able to do my analysis part. But i get with median survival values in data summary section. It would be helpful if you explain the data summary n how it calculate median survival.
#blank lines in data summary section affects median survival values?? its actually affecting it in my analysis.. please help
Informative
Good! Thanks
Hi. thankyou for your useful video. How can I add the data if there are replicates for each treatment?
With deaths each replicate is handled as a separate timeline, just add more events to the sheet.
@@DoryVideo Thanks for the video and the answers to our questions. I do not understand how to do if I have replicates, there is no way to differentiate between them? For example, I have 3 controls and 3 treatments, so I would like to make a table with each replicate and then analyze if any of the controls, for example, have abnormal values (which is exactly what I observe but I need to substantiate it with statistics). If I put all the data in the same column, don't I lose the "individuality" of each replicate?
Sorry, this might be a dumb question. i am trying to do a survival analysis with insects and i have 70 insects in each treatment group and i have number of death for each day! how should i proceed with it
Hello, what if we have only one group of N = 30. If like day 15 if more than 3 died how do you include your 1 & 0?
Just put day 15 three times and three 1s, one for each death
Thank you for the quick response! I understood it now.
Hi, my supervisor asked me to put P value and significance on graph. How could be this possible on prism?
Simply add an annotation
Can someone explain how to do cox regression
