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
Objectives: To assess the diagnostic value of tuberculosis-secreted Ag85B, ESAT-6 and CFP10 in pulmonary tuberculosis. Method: Immunohistochemical (IHC) and acid-fast staining were performed, the detection efficiency of the two methods were analysed with chi-square test. Results: Acid-fast staining demonstrated a sensitivity of (18/69, 26.09%) and a specificity of 100%. IHC staining for Ag85B, ESAT-6 and CFP10 was positive in all 18 cases with positive acid-fast staining and additionally positive in 25,36 and 30 cases, respectively, that were acid-fast-negative. The sensitivities of IHC staining for Ag85B, ESAT-6 and CFP10 were 62.32%, 78.26% and69.57%, respectively, while their specificities were 86.57%, 85.07% and 91.04%, respectively. Joint antigen analysis revealed that simultaneous positivity for two or three of Ag85B, ESAT-6 and CFP10 increased specificity (95.52% to 100%) but decreased sensitivity (49.28% to 62.31%). The presence of any one of the three antigens elevated sensitivity (81.16% to 88.41%) but lowered specificity (68.66% to 77.61%). Specificity reached 100% for concurrent positivity of all three antigens, while a sensitivity of 88.41% was observed for positivity of any one antigen. Conclusions: Ag85B, ESAT-6, and CFP10 exhibits greater sensitivity in pulmonary tuberculosis and combined antigen testing enhances the diagnostic accuracy.
