HIV and Tuberculosis Coinfection in Brazil: Cohort Profile Monitored by the Unified Health System (2015-2018).
Observational study in Journal of community health, 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
To describe the sociodemographic and clinical profile of individuals with HIV-tuberculosis coinfection followed in services of the Brazilian Unified Health System (SUS), through the integration of data from the Qualiaids-Brazil Cohort and national health information systems.
methodsNationwide observational study using data from the Qualiaids-BR Cohort, composed of people living with HIV/AIDS (PLWHA) who initiated antiretroviral therapy (ART) between 2015 and 2018 in SUS services participating in the Qualiaids 2016/2017 survey. Individuals with at least one episode of active tuberculosis after ART initiation were included.
resultsA total of 7,747 individuals with HIV-tuberculosis coinfection were identified. The majority were men, young, mixed-race, with low educational levels, and residing in the Southeast region. Social vulnerabilities included alcohol, tobacco, or illicit drug use (> 20%). Half presented an initial viral load > 100,000 copies/mL and 60% had baseline CD4 counts < 200 cells/mm³. Regarding tuberculosis, 80.3% were new cases, 9.5% re-entries, and 5.7% relapses. Treatment duration was concentrated between 6 and 12 months, with a cure rate of 70.9% and abandonment in 10.4% of cases, of which 21.3% also discontinued ART.
conclusionData integration enabled a comprehensive profile of HIV-tuberculosis coinfection, consistent with national findings and marked by social vulnerabilities that impact adherence and outcomes. The high proportion of treatment abandonment, also associated with ART discontinuation, highlights systemic weaknesses and the need for integrated care strategies for individuals with HIV-tuberculosis coinfection. The findings reinforce the importance of promoting comprehensive and continuous care to mitigate the impacts of coinfection.
