I've been working on a table with several multicolumns and multirows. Though the table is almost done, there are some details that I'm not very confortable. I don't think the last row Exarcebations requiring oral corticosteroids is really good.
Can someone help me doing it better? I would also like to separate the persistent columns though the last row wouldn't have separator.

Any ideas for improvement?
Thank you very much

, it should compile and contain close to the minimal amount of code needed to explain/demonstrate what you are asking. This saves everyone time and makes it easier to help you:)
