Accuracy of multitarget indirect enzyme-linked immunoassay assay for detection of tuberculosis antibody.

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
backgroundDiagnosis of tuberculosis (TB) is still difficult. The development of rapid and sensitive laboratory tools for the diagnosis of tuberculosis is a priority. This study aimed to develop an indirect enzyme-linked immunoassay (ELISA) assay for detection of TB antibody and explore its diagnostic value in patients with pulmonary tuberculosis (PTB) via a multi-center clinical evaluation.
methodsThe specific antigen, fusion antigen, and specific antibody peptide were obtained using molecular cloning and phage peptide library screening. An indirect ELISA assay was developed using multiple target materials. Further, the assay was validated in six institutions with clinically confirmed TB patients, non-TB patients with pulmonary disease, and healthy controls as research subjects.
resultsAn indirect ELISA assay was developed with 16 kD antigen, 11,488 (CFP10-MPT48-TB8.4) fusion antigen, and TB18 and pl2 as target antigens against TB antibody. The results of this multicenter study showed that the sensitivity, specificity, and the area under the receiver operating characteristic curve (AUC) of the assay were 48.25% [95% confidence interval (CI): 45.5-51.1%], 92.20% (95% CI: 90.7-93.5%) and 0.724 (95% CI: 0.707-0.741), respectively, and the cut-off value was 0.119. According to the meta-analysis, the combined ROC was 0.736 (95% CI: 0.692-0.779), I
conclusionsMultitarget indirect ELISA assay based on specific-TB antigen, fusion antigen, and antibody peptide is of value for the diagnosis of PTB and can be used as an auxiliary rapid diagnostic tool to improve the sensitivity of sputum-negative TB.
