Performance of Xpert MTB/RIF for Diagnosis of Tuberculosis in HIV-Infected People in China: A Retrospective, Single-Center Study.
Article in Medical science monitor : international medical journal of experimental and clinical research, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
BACKGROUND There are few studies of GeneXpert MTB/RIF (hereafter referred to as Xpert) detection technology in HIV-infected people in China. Therefore, this study aimed to evaluate the value of Xpert in HIV/TB co-infected patients and to provide reference and guidance for the diagnosis of TB in HIV-infected populations. MATERIAL AND METHODS This study reviewed medical records of human immunodeficiency virus (HIV) patients hospitalized at the Infection Center of Beijing Ditan Hospital affiliated to Capital Medical University from January 2018 to May 2020, and patients diagnosed with pulmonary and extrapulmonary tuberculosis were screened as study subjects. Sensitivity and specificity of Xpert were analyzed using ROC curves. RESULTS Of the 413 HIV patients, 177 patients met the entry criteria, of which the diagnosis was active pulmonary tuberculosis (PTB): 145 and extrapulmonary tuberculosis (EPTB): 32. The sensitivity of Xpert for PTB and EPTB was 82.0% and 100%, higher than that of acid-fast bacilli (AFB) (61.0% and 58.3%), and slightly lower than that of T-SPOT.TB (91.0% and 100%); the specificity was 83.7% and 93.5%, higher than that of AFB (72.6%, 87.1%) and T-SPOT.TB (16.6%, 21.2%). The sensitivity of Xpert was 100% in bronchoalveolar lavage fluid (BALF) and 80.0% in sputum; in patients with CD4⁺ <200 cells/mm³, the sensitivity of Xpert was 90.0% and specificity was 84.8%, higher than that of AFB (60.0%, 75.5%) and T-SPOT.TB (90.0%, 21.5%). CONCLUSIONS Xpert has a high accuracy in HIV/TB co-infected patients, and Xpert still shows a high sensitivity and specificity even in HIV patients with CD4⁺ <200 cells/mm³. Xpert is recommended for the diagnosis of tuberculosis in HIV-infected patients.
