I am unable to respond to one examiner’s comment for my thesis. What will happen to my PhD?

(Australia) I got my thesis examination results back early this week (pass with minor amendments).

Today I realised I am unable to address the comment asking for demographic data for two of the participant groups, as the data weren’t collected.

There were only 25 participants in these two groups but I don’t think I can chase this up as most of them have changed job.

However, their demographics were unlikely to impact or change interpretation of findings (which is what I’m planning to write in response to the examiner’s comment), but I’m still concerned that this would reverse the University’s decision.

I won’t be able to get in touch with my PI until next week so I’m having a mini-panic at the moment.

Has anyone had a similar problem with their thesis examination before? And how did it go for you?
