From the Discussion section: "Patients with long COVID had elevated levels of IL-8, GFAP and TGFβ, with TGFβ specifically increased in the cohort with brain fog. GFAP is a robust marker of cerebrovascular damage and is elevated after repetitive head trauma, reflecting BBB disruption, as seen in...

This caught my eye in the Supplementary Information, pp. 9-10: "Motivation was assessed using the Effort-Expenditure for Rewards Task (EEfRT) which assesses effort, fatigue, and reward sensitivity (Figure S5A) [...] multiple models were evaluated to assess for group differences and assess for...
