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
In this study, the trastuzumab-functionalized SK-BR-3 cell membrane-wrapped mesoporous silica nanoparticles loaded with pyrotinib (Tra-CM-MSN-PYR) were prepared for targeted therapy of HER2-positive breast cancer. Transmission electron microscopy (TEM) characterization showed that MSN had a spherical morphology with mesoporous channels and that the structure of Tra-CM-MSN was a cell membrane (CM) layer successfully coated on the surface of MSN. A cellular uptake assay demonstrated that FITC-labeled Tra-CM-MSN were taken up by SK-BR-3 breast cancer cells, which illustrated that Tra-CM-MSN had good targeting ability compared with CM-MSN and MSN. In vivo imaging experiments demonstrated significant accumulation of FITC-labeled Tra-CM-MSN in tumor tissues, further proving that Tra-CM-MSN have superior targeting properties. Cell apoptosis experiments suggested that Tra-CM-MSN-PYR significantly inhibited the proliferation of SK-BR-3 breast cancer cells. The results of in vivo animal experiments also showed that Tra-CM-MSN-PYR significantly inhibited tumor growth. These results indicate that Tra-CM-MSN-PYR has potential application as a targeted therapy for HER2-positive breast cancer in the future.
