Dear Statalisters,

I am currently trying to calculate how many subjects that have a least follow-up time as defined by the median and inter-quartile range (25% and 75% percentile) of my dataset. I've tried several commands such as stptime, stci, stsum but I am not sure whether they give me an estimate of how many subjects are still not censored in the dataset at a certain time, or if this reported as no. of individuals with least follow up time.

I've read several posts in this forum and several help files in Stata without finding a good solution to this. It's surely an easy solution to this, but I'll appreciate any help and guidance.

Thanks!

Kind regards,
Håkon
