Neurological and neuropsychiatric manifestations of post-COVID-19 condition in South America: a systematic review of the literature.
Synthesis in Arquivos de neuro-psiquiatria, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 2 papers, 1 of them a synthesis that pooled it.
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 post-COVID-19 condition is a major modern challenge in medicine and has a high global impact on the health of the population.
objectiveTo determine the main neurological and neuropsychiatric manifestations after acute COVID-19 infection in South American countries.
methodsThis is a systematic review study, registered on the PROSPERO platform following the PRISMA model. 4131 articles were found with the search strategies used. Neurological and neuropsychiatric manifestations were investigated in individuals three months or more after acute COVID-19 infection, and older than 18 years, including studies conducted in South American countries published between 2020 and 2022.
resultsSix studies (four from Brazil and two from Ecuador) were analyzed. Regarding the type of study: three were cohorts, two were case reports, and one was cross-sectional. The main outcomes found were new pain (65.5%) and new chronic pain (19.6%), new headache (39.1%), daily chronic headache (13%), paresthesia (62%), in addition to neuropsychiatric diseases, such as generalized anxiety disorder (15.1%), post-traumatic stress syndrome (13.4%), depression and anxiety (13.5%), suicidal ideation (10.1%), and several cognitive disorders.
conclusionNeurological and neuropsychiatric manifestations related to depression and anxiety, and cognition disorders are reported during the post-COVID-19 condition in South America. Symptoms associated with chronic pain appear to be associated with the condition. More studies on post-COVID-19 conditions are needed in the South America region.
