In my study i have baseline and 3 follow-up timepoints (4month, 6-month, 12-month). I have participants who don't have a score for every follow-up timepoint. But i want to say 'Yes' if any of the follow-ups have a <= -3 change from baseline. And 'No' if any have >-3 instead. But somehow the code is producing Yes/No for only participants that have data across all timepoints. For example, in ROW7, there is a participant with just the 4month score but they have a >-3 score from baseline, which should produce 'No' but the column is empty. I tried many different codes but cannot understand what I am doing wrong. Please help!

Here is my current code: IF(4month - baseline <= -3 or 6month - baseline <= -3 or 12month - baseline <= -3, 'Yes', IF(4month - baseline > -3 or 6month - baseline > -3 or 12month- baseline > -3, 'No', 'No'))

Edit: I tried ignore_missing=1 but it doesn't seem to work in IF() functions (see photo below)

I think the problem is that your code is expecting data to be present (either above or below a set value) - however, as these cases have an absence of a value, your code doesn't take this into account and so the outcome is left blank. Try including a reference to 'ignore_missing' or such like in your code and this might then include those with some blank columns.

Hello, I've tried that too but it seems to only work outside of IF() functions. I've updated a screenshot of the error message it gave me when I tried to do that.

Hey @statsdontlie,
would you like to take a look at the screenshot, i put a suggestion that might be what you are looking for to compute your new variable. Cheers,
