Relationship between long covid and functional disability in adults and the seniors in the south of Brazil.
Article in BMC public health, 2025. 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
backgroundIndividuals living with long COVID experience a range of symptoms that affect their ability to carry out daily activities or participate in social and community life. This study aimed to analyze association between functional disability and the occurrence of long COVID symptoms, as well as to analyze the effect of symptom persistence time on functional disability.
methodsThis is a cross-sectional study using data from the SulCovid-19 study, which interviewed individuals who had COVID-19 between December 2020 and March 2021. The functional disability outcome was assessed using the Basic Activities of Daily Living (BADL) and Instrumental Activities of Daily Living (IADL) scales, while the exposures were the symptoms of long COVID. Adjusted analyses between outcomes and exposures, stratified by time after the acute phase of infection, were performed using Poisson regression with robust variance adjustment.
resultsThe prevalence of BADL disability was 4.8% (95%CI 4.0;5.6), and for IADL disability, it was 8.4% (95%CI 7.4;9.4). The main symptoms associated with BADL disability were dyspnea, dry cough and sore throat, while for IADL, they were joint pain, muscle pain, loss of sensation, nasal congestion, sore throat and runny nose. When stratified by tertiles of time after the acute phase of infection, a relationship was found between BADL disability and dyspnea, ageusia and, nasal congestion in the 3rd tertile, while only ageusia was found to be related to IADL disability in the 3rd tertile.
conclusionsLong COVID symptoms were associated wiht limitations in the functional capacity of adults and the seniors. The findings can be used to guide the care and rehabilitation of individuals with disabilities who have had COVID-19, particularly for referral to appropriate health professionals.
