I wouldn't call it simplicity, because what if on day 5 I have 1000 survivors? Do I need to enter zero 1000 times? There must be other option. For example I have already % of survivors at certain hours post infection and I don't see the point in changing it back to numbers of survivors.
this is a survival graph. It tells you how many animals survive at a particular point of time, not how many died. This graph shows that in group A at day 5, 4 animals survive. clear?
@@debasishroy1351 Yeah, but he calculated differently on the other group. Ha said one death happened in day 5 on Group A and added 4 - 1. Than in Group B death happened on the 2nd day and he added 2-1. So either this or that solution but there's definitely an error in it, which on is the wrong is the question....
Hi great video- was wondering do you do ny personal tutoring? also was wondering how would you code the data for larger numbers, eg my experiment involves survival rate of celegans exposed to a restricted diet!!! however my basal rate starts at 330, so subsequent weeks involve large deaths, how would I plot this in prism please x
hi! what if my data is in percentage? can I input the data in the form of percentage in different time points? I am looking at the survival of cells not patients.. thank you
Good question. I've not ever needed to enter data in that way. If you have data as a % you may have problems with the plotting of the data as that is not the way Prism is designed to handle the data. I'll check and get back to you.
@@DoryVideo Hi, a consultation to make graphics for example of brine shrimp, they will be born by day and there will be days that are born but die, this same prism software can I use it? because I don't know which one to use or what graphic please help me. Thank you.
I have a question. Your data has day 1-5 but I have the survival days ranging from 1-36 how can I put this kind of data in the excel file? Thanks for the nice tutorial.

I have the same problem. Any solution?
I agree with Constantine because at day 5 group A loss animal not at day 4
In day 5 we lost a subject in group A not in day "4"
I'm pretty sure there's an error here. Group A loses an animal on day 5, not on day 4...
I agree with you.

You are right.

As far as analysis goes, is there a way to find the confidence interval and hazard ratio? Or does prism use 95% CI?
For the Group A" shouldn't it be 5 - 1 instead of 4 - 1, since the death happened on the last (5th) day?
This was very helpful! Thanks for the quick and easy tutorial!
I'm sorry but this is so confusing. I almost would rather do the calculations myself by hand. Lol

Thank you for this simpler explanation. Very much helpful for me.
Hi,
Thanks for the video, very helpful,
How you enter the data if you lose more than one patient a day?
Just put in the day twice with a 1 in each line

Thank you for the detailed explanation! Can you please guide me on how to add the 'n at risk' table below the graph?
Awsome! Very helpful! Thanks!
Thanks! Please subscribe to get updates when I add more!
It is much better to do standard (normal) graph. Much easier and faster than this struggling.
Survival (Kaplan-Meier) Curves in Graphpad Prism
Very useful, thanks very much.
Thanks a lot for such a helpful tutorial. great work
thanks, it is very helpful
excelente. thank you.
My pleasure!

@@DoryVideo could you answer me please?
I am sorry I cannot help everyone who asks analysis questions.
How do you make the number at risk table in Prism?
Thanks, it does it automatically when you do the KM analysis
I have a question. Your data has day 1-5 but I have the survival days ranging from 1-36 how can I put this kind of data in the excel file? Thanks for the nice tutorial.
You enter it in exactly the same way just extending the time line to the end of your study
Thanks it worked!
This is very helpful; just what I needed to know!
Great!
great job
Nice
