Hello!
I have a query (which might be very stupid) with regards to the Kaplan-Meier failure graph (using sts graph) and the risktable command.
Let's hypothesise that I have a dataset of 100 people with a follow-up of 90 days. Unfortunately for 2 of them there are only information at time 0, because afterwards they were lost to follow-up. Is it correct that the risktable of the sts graph shows as follows with 98 as number of people at risk at time 0 or it should be 100?
Thank you in advance!
