Maybe? Reading the abstract, it seems to make sense to me how this paper ended up in this specific journal. From what I understand, the authors were specifically looking at one ophthalmology-related long COVID symptom (impaired retinal microcirculation) and found a common marker that is linked to that symptom. Granted, I have 0 experience in any medical field, but it doesn't immediately look like a red flag to me?
