There is not that much context here, so I will do a standard answer too. If you have a doubt regarding the data owned by a node, running repair takes some resources but should never break anything. I mean it is an operation you can be running as much as you want. So I would use it, just in case.
If the repair finishes successfully, your data is now consistent.
