Cognition and Long COVID: a Review.
Review in Current neurology and neuroscience reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purpose of reviewProvide an overview of current knowledge regarding cognitive issues in patients with long COVID, also termed brain fog or cognitive COVID. RECENT
findingsSubjective cognitive symptoms in long COVID patients are common but often go undetected by traditional standardised cognitive test batteries. This discrepancy poses a major clinical and societal problem, given the prevalence, protracted course and impact of cognitive COVID on work functioning. New, online assessment methods for cognitive function are feasible and corroborate subjective self-report symptoms, finding executive function impairments in cognitive COVID. As vaccination protects against brain fog and not against anxiety and depression in long COVID, brain fog can be seen as a core symptom of long COVID, concerning executive functioning, and a direct effect of neurotropic viral brain infiltration. Depression and anxiety are comorbid conditions due to indirect factors associated with the pandemic, such as increased social isolation and loss of work. Ongoing vaccination programs should not only target the elderly, but also working-age people. Online cognitive assessment batteries are recommended for assessment and treatment monitoring in long COVID. Integrated care is recommended given the high rate of multimorbidity. Future research might explore the effects of antiviral medication, modulation of the immune response, and GLP-1 agonists in long COVID.
