Post-COVID-19 functional status in socioeconomically vulnerable neighborhoods attended in primary health care in two Brazilian cities: a cross-sectional study.
Article in BMC infectious diseases, 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
backgroundThe prolonged effects of COVID-19 present social costs and pose challenges to public health infrastructure, necessitating the implementation of public policies for comprehensive post-COVID-19 care.
objectiveThis study aimed to assess post-COVID functional status and associated sociodemographic factors and health inequalities among residents of socioeconomically vulnerable neighborhoods who attended primary health care in two Brazilian cities.
methodsA cross-sectional study was conducted from July 2022 to July 2023 in Salvador and Rio de Janeiro. We included participants who sought COVID-19 tests in primary health care services, had previously contracted COVID-19, and completed the post-COVID-19 functional status scale. Post-COVID syndrome was classified as none, negligible/slight, or moderate/severe. Sociodemographic characteristics, health conditions, and access to health services were analyzed as explanatory variables. Descriptive and bivariate analyses were performed. Using multinomial logistic regression, we estimated the adjusted odds ratios (aORs) and their 95% confidence intervals (95%CIs).
resultsAmong the 3,067 participants, the overall prevalence of post-COVID functional limitations status was 34.6% (26.7% and 7.9% reporting negligible/slight and moderate/severe, respectively). The following variables were associated with moderate/severe functional status: living in households with fewer rooms (aOR = 1.66, 95%CI: 1.23-2.24), female gender (aOR = 1.57, 95%CI: 1.14-2.16), older age (aOR = 1.02, 95%CI: 1.01-1.03), self-reported diabetes mellitus (aOR = 1.78, 95%CI: 1.17-2.69), respiratory diseases (aOR = 2.59, 95%CI: 1.56-4.29), having contracted COVID-19 two or more times (aOR = 1.57, 95%CI: 1.15-2.14), not having had a medical appointment in the last 12 months (aOR = 1.70, 95%CI: 1.24-2.33), difficulty accessing COVID-19 testing (aOR = 1.63, 95%CI: 1.05-2.52), and experience discrimination in health services (aOR = 2.85, 95%CI: 1.87-4.35).
conclusionsOur findings indicate varying degrees of post-COVID functional limitation status among residents of socioeconomically vulnerable neighborhoods who have recovered from COVID-19. People who live in homes with fewer rooms, are female, older, have pre-existing diabetes or respiratory diseases, have been reinfected with COVID-19, have difficulty accessing COVID-19 testing and those who experienced discrimination in health services are at higher chance of developing post-COVID syndrome.
