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: Troponin is an important marker for the diagnosis of acute myocardial infarction (AMI). The detection of troponin in peripheral blood is simpler and more convenient than that in venous blood, which has attracted more and more clinical attention. The purpose of this study is to establish a novel method for the rapid detection of high-sensitivity troponin I (hs-cTnI) in peripheral blood by quantum dot fluorescence immunoassay and evaluated the clinical accuracy of the method. Methods: A total of 90 patients with chest pain admitted to Wuxi Second People's Hospital of Nanjing Medical University had peripheral blood and venous blood samples collected for detection of hs-cTnI by rapid quantum dot fluorescence immunoassay. The differences between the two methods were evaluated, as well as the analytical performance and clinical diagnostic efficacy of hs-cTnI detection by quantum dot fluorescence immunoassay. The final diagnosis was determined by two independent cardiologists. Results: This study verified the precision, linear range and sensitivity of the novel detection method. There was good correlation between the results of hs-cTnI quantum dot fluorescence immunoassay for peripheral blood and the results for venous blood (regression equation Y=1.026x+0.521, R Conclusions: Rapid detection of hs-cTnI by quantum dot fluorescence immunoassay in peripheral blood is feasible. It has a high correlation and consistency with the venous blood method, as well as a high clinical diagnostic value for AMI and is more convenient and easier to detect.
