Psychopathological, neuropsychological and sociodemographic description of the population using a post-COVID outpatient clinic: results from the 2Long4COVID BLOOD study.
Article in European archives of psychiatry and clinical neuroscience, 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
backgroundThe prevalence of post-COVID syndrome (PCS) is estimated to be below 1%, with notable variation across different SARS-CoV-2 variants. The syndrome is characterized by a broad spectrum of clinical manifestations affecting multiple organ systems. Cognitive impairments and psychological distress are frequently observed; however, their underlying pathophysiological mechanisms remain poorly understood.
objectiveThis study examines the sociodemographic, psychopathological, and neuropsychological characteristics of patients treated at our psychiatric post-COVID outpatient clinic (PPCO-clinic).
methodPatients were recruited from the post-COVID outpatient clinic of the Department of Infectious Diseases at Cologne University Hospital. Assessments included observer-rated evaluations, neuropsychological testing, and psychopathological examinations. Data from 41 patients were analyzed and compared with normative data from healthy controls reported in the literature.
resultsBetween April and November 2022, 42 patients attended the PPCO-clinic, with 41 included in the analysis (58.5% female; mean age: 45 years). Patients exhibited significantly poorer performance across all neuropsychological tests compared to healthy controls, with pronounced deficits in visual memory, phonematic fluency, visuomotor function, and global cognitive screening. Additionally, they reported significantly higher levels of depression, anxiety, daytime sleepiness, fatigue, and reduced quality of life. Personality assessments revealed increased neuroticism and lower extraversion, conscientiousness, and agreeableness.
conclusionThese findings underscore the importance of comprehensive neuropsychological and psychopathological assessments in individuals with PCS-particularly in cases where symptoms persist beyond the scope of routine primary care-to ensure accurate evaluation and effective management.
