Analysis of the diagnostic efficacy of targeted next-generation sequencing for tuberculosis in patients with HIV.

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
Background: To evaluate the diagnostic performance of targeted next-generation sequencing (tNGS) for tuberculosis (TB) in patients with human immunodeficiency virus (HIV) and to compare it with traditional diagnostic methods. Methods: A total of 66 HIV patients were enrolled, including 25 with confirmed TB infection and 41 without TB. Statistical analyses were performed using SPSS 22.0. Diagnostic performance was assessed using the chi-square test. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), Kappa coefficient, and the area under the curve (AUC) of the receiver operating characteristic curve (ROC) were calculated for tNGS. McNemar's chi-square test was used to compare the diagnostic efficacy of tNGS with other methods. Results: The sensitivity, specificity, PPV, NPV, AUC, and Kappa of tNGS were 76.00%, 100.00%, 100.00%, 87.20%, 0.880, and 0.797 respectively, all superior to traditional methods. When combined with Xpert, the sensitivity increased to 84.00%, and the AUC improved to 0.920, indicating strong diagnostic complementarity. Conclusion: tNGS exhibits high sensitivity and specificity for diagnosing TB in patients with HIV. Notably, the combination of tNGS with Xpert further enhances diagnostic efficacy, underscoring its potential clinical promotion value.
