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
objectiveTo prepare S2.2/DOX magnetic nanoliposomes by combining the potential benefits of MNPs in MRI and the targeted performance of nano-drugs as an innovative method for integrated diagnosis and treatment of breast cancer (BC).
methodsWe created a S2.2-PEG-MZF/DOX molecular probe by using a lipid material to encapsulate PEG-MZF-NPs and doxorubicin (DOX), and a S2.2 aptamer to target MUC1 to conjugate with PEG-MZF/DOX nanoliposomes. The potential of probe for cell-specific targeting and magnetic resonance (MR) molecular imaging was evaluated by MR scanner and Prussian blue staining. Additionally, we explored the feasibility by using nanoliposome magnetic induction heating to interfere with MCF-7 (MUC1+) BC cells under the influence of an alternating magnetic field (AMF).
resultsPEG-MZF-NPs were biologically safe. The T2 relaxation rate of PEG-MZF-NPs was found to inhibit T2 signal in a concentration-dependent manner, and the T2 signal of the S2.2-PEG-MZF molecular probe in MCF-7 cells was significantly lower than that in PEG-MZF-NPs group. Moreover, the T2 signal reduction was more pronounced in MCF-7 cells than in the hepatoma cell line HepG2 (MUC1-), suggesting a strong MRI potential of the S2.2-PEG-MZF molecular probe. The S2.2-PEG-MZF/DOX nanoliposome was able to achieve the desired temperature range for tumor hyperthermia (42-44 °C) in vitro. The S2.2-PEG-MZF/DOX nanoliposome accompanied by magnetic fluid hyperthermia (MFH) could inhibit proliferation and invasion and induce apoptosis of MCF-7 cells. The effects of this approach were significantly higher than those observed in the other groups.
conclusionWe successfully developed a novel technique for BC diagnosis and treatment using thermochemotherapy under the guidance of MR molecular imaging. This approach holds great potential for improving the management of this devastating disease in the future.
