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
This multicenter prospective study was conducted to assess high-sensitivity troponin T (hs-TnT) and other biomarkers to decide and predict culprit lesions indicated for emergency percutaneous coronary intervention (PCI) in patients with suspicious acute coronary syndrome (ACS). We have reported Hs-TnT is the most sensitive biomarker for earlier diagnosis and decision making in patients with suspected ACS. In this study, we had conducted subanalysis investigating the usefulness for prediction of ACS culprit lesion. The patients with suspicious ACS and initially negative whole-blood rapid troponin T test, who underwent coronary angiogram (CAG), were enrolled (n = 74). Hs-TnT, quantitative assay for conventional troponin T (c-TnT), creatine kinase MB isozyme (CK-MB), and heart-type fatty acid-binding protein (H-FABP) were simultaneously measured. ACS culprit lesion was described as total occlusion, subtotal occlusion, and/or angiographical unstable lesion such as thrombosis, ulceration or irregularity. The CAG revealed that 49 cases had ACS lesions to be indicated for emergency PCI. The areas under the ROC curves and ROC-optimized cut-off of hs-TnT, c-TnT, CK-MB, and H-FABP were 0.75, 0.67, 0.68, and 0.75, respectively, and 18, 11, 2.0, and 4.6 ng/ml, respectively. In patients with total occlusion and 90-99 % of diameter stenosis (TIMI 2 or 3), hs-TnT could predict emergency PCI with significantly higher sensitivity compared with H-FABP (hs-TnT >14 ng/ml; 71 %, and H-FABP >6.2 ng/dl; 51 %, p = 0.021) and other biomarkers. Meanwhile, H-FABP displayed significant correlations with number of diseased vessels and presence of thrombotic lesion. The present study first revealed different characteristics of correlation between the angiographic culprit lesions and each cardiac biomarker. For prediction of ACS lesions requiring emergency PCI, hs-TnT had the highest sensitivity with satisfied analytical precision.
