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
Vasorin (VASN), a transmembrane glycoprotein, plays a pivotal role in hepatocellular carcinoma (HCC) progression by regulating cell proliferation and migration. However, its subcellular localization and organelle-specific functional mechanisms remain inadequately defined, mainly due to the limitations of ultrastructural resolution and quantitative analytical techniques. In this study, an optimized immunoelectron microscopy protocol (IEM-VASN) was developed, combining 4% paraformaldehyde-0.5% glutaraldehyde fixation and a 1:200 anti-VASN antibody dilution, achieving an optimal balance between structural preservation and antigenicity. This method enabled the precise detection of VASN depletion in Huh7-KD cells (p < 0.0001) and Vasn
