Wiki Abbreviation help needed: O/E

[MeanderingMichigander]

I use the website www.icdlist.com a lot because they have the most comprehensive list of synonyms for ICD-10 codes I've found.

However, on several lists they include the abbreviation O/E, and I just can't figure it out.

​

Example from: https://icdlist.com/icd-10/R29898
​

Does anyone here know what it means??

Thanks!!

In the context of abnormal findings, I think it means 'on examination'.

O/E generally stands for "observed or expected".
