Unable to see Median Survival while making KM Curve
Hello everyone, I'm very new to JASP. I was trying to make a KM Curve for my project and I followed a video (https://www.youtube.com/watch?v=x8Pbcd7TSwE) to make it.
I know I don't have much data but it seems from that video, I don't need to? But I wanted to ask you all how come the median survival was not computed for the data. In addition, it says 13 observations were ommited, but I don't know which observations but from my data, they're not missing? Here is my data below. My friend put my data in SPSS and we came out with the same KM curve at least, so that's why I'm not sure what happened to the Summary Table.
Appreciate any and all help, thanks!

Strange. It may be that you have 13 rows underneath that contain no values but are there nontheless?
I'll ask out expert about the missing median
Hi pandakupo,
I managed to reproduce your analysis up to the missing data issue. Could you share your JASP file or your settings?
The reason why you don't see the median is because the observed survival never drops below 50%. As such, the non-parameteric model cannot provide the estimate. This is nicely visible once you explore the survival curves
