How do I interpret a global proportionality test using Proc PH Reg

Hello! I need help with this slide from my lecture. Namely, what is being conveyed by the global proportionality test. I have scoured both my two textbooks and found nothing on it. Not to be rude to my professor either, he just isn't the greatest lecturere (he's hard to understand 🤐). Also, did he make a mistake in where the proportional hazards model holds? The significance test shows grade and nodes to be significant, not the ones he is saying the proportional hazards assumtion holds for. Does the Global test override this?

This isn't homework, I just need someone to explain it better than he did.

Do you have the syntax for the SAS procedure that was used to create the table? If so, please post it. By knowing the procedure, options, and model, it will be easier to interpret the results.
