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
purposePrecise tumor excision is important but challenging in breast-conserving surgery (BCS). Tumor-specific fluorescence imaging may be used for intraoperative tumor detection and, therefore, to guide precise tumor excision. The aims of this study are to develop a glucose transporter 1 (GLUT1)-targeted near-infrared fluorescence tracer and evaluate its accuracy for breast cancer detection using fresh surgical breast specimens.
methodsBioinformatic analysis was performed to compare GLUT1 expression between breast cancer and normal breast tissues. A GLUT1-targeted fluorescence imaging tracer WZB117-CY7.5 was developed. In combination with fluorescence imaging (FMI), its binding specificity to GLUT1 was examined in in vitro breast cancer cell experiments, in vivo 4T1 breast tumor-bearing mouse models, and 60 freshly resected human breast tumor tissues. The diagnostic accuracy of WZB117-CY7.5, was evaluated in fresh specimens derived from 60 patients diagnosed with breast cancer.
resultsGLUT1 expression is higher in breast cancer tissues compared with normal tissues. WZB117-CY7.5 specifically bound to breast cancer cells in in vitro cell experiments and accumulated in tumor areas in a 4T1 tumor-bearing mice after intravenous injection by FMI. Moreover, WZB117-CY7.5 specifically bound to freshly resected human breast cancer and demonstrated excellent diagnostic performance in discriminating breast cancer, irrespective of cancer subtype, from normal breast tissue on fresh surgically resected breast tissues.
conclusionsWZB117-CY7.5 showed high accuracy in intraoperative breast cancer detection, irrespective of the cancer subtype. This highlights its potential for clinical applications as a generic tracer for fluorescence image-guided surgery (FIGS) in BCS and fluorescence image-guided pathology for tissue sampling.
