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
objectiveTo analyze the factors associated with the frequency of false negative results for the RMT-TB test for the diagnosis of pulmonary tuberculosis in the state of São Paulo.
methodsCross-sectional study using pulmonary tuberculosis cases from the state of São Paulo reported in the TB-WEB system between 2014 and 2023. RMT-TB results were compared with sputum smear microscopy, sputum culture, and sensitivity testing. Subsequently, variables with p<0.05 in the statistical tests were included in the logistic regression.
resultsThere was a significant increase in the use of RMT-TB over the years, reaching 76% of cases in 2023. Analysis of the test accuracy revealed high agreement with sputum culture (82.6%) and the sensitivity test (98.4%), although it showed lower agreement with sputum smear microscopy (78.5%). The study identified factors associated with false-negative results on the RMT-TB, such as advanced age, female sex, HIV status, imprisoned, and a normal chest X-ray. Logistic regression confirmed that these factors increase the likelihood of false-negative results.
conclusionThe RMT-TB is an effective tool for diagnosing pulmonary tuberculosis, but the interpretation of results must consider each patient's specific risk factors, especially in high-risk populations. The study highlights the importance of combining the RMT-TB with other diagnostic methods and clinical evaluation to ensure accurate diagnosis and appropriate treatment.
