Prevalence of tuberculosis/COVID-19 co-infection and factors associated with SARS-CoV-2 infection in pulmonary tuberculosis patients at a respiratory diseases center: a cross-sectional study.
Article in The Pan African medical journal, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Introduction: currently, tuberculosis (TB) is the second cause of infectious disease-related deaths before COVID-19. These two infections have several similarities but little data is available on TB/COVID-19 co-infection, hence, we sought to investigate the prevalence of this co-infection and the factors associated with Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection in tuberculosis patients in a tuberculosis-endemic area. Methods: we conducted a prospective cross-sectional study from January to June 2022 at Respiratory Diseases Center in Douala, Cameroon by enrolling all consenting pulmonary tuberculosis patients. The presence of SARS-CoV-2 ribonucleic acid (RNA) and gamma-interferon levels were laboratory analyzed using the Reverse Transcriptase-Polymerase Chain Reaction and the enzyme-linked immunosorbent assay (ELISA) technique, respectively. The factors associated with COVID-19 carriage in pulmonary tuberculosis patients were analyzed by logistic regressions. Results: overall, we enrolled 185 patients; 57.8% were males (sex ratio of 1.36) and their mean age was 43.70 ± 17.89 years. The prevalence of SARS-CoV-2 RNA in pulmonary TB patients was 24.3%. Asthma and sore throat were the factors favoring carriage (OR=3.74; 95% CI=1.271-11.017; p=0.017 and OR=4.05; 95%CI=1.204-13.600; p=0.024) and cough was a protective factor (OR=0.15; 95% CI = 0.034-0.690; p=0.015). Conclusion: the prevalence of SARS-CoV-2 carriage in tuberculosis patients is high and greater than the national prevalence. Asthma and sore throat would be associated factors.
