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
A novel glycoprotein assay was developed by integrating the hairpin aptamer (H-APT)-mediated glycoprotein recognition and the reactive oxygen species-sensitive microcapsule (ROS-MC)-induced signal amplification. The analyzing process begins with the transfer of the target glycoprotein to a chlorin e6 (Ce6)-labeled DNA sequence via H-APT-mediated DNA displacement. Subsequently, the Ce6-labeled DNA was used to induce the disassembly of fluorophore-loaded ROS-MC under 650-nm light irradiation. Leveraging the rapid release of the fluorophore and the high loading capacity of the MC, this glycoprotein assay is capable of quantifying glycoprotein content in native biofluids within 2.5 h, achieving a detection limit of 0.034 ng/mL. We applied this assay to determine the glycoprotein composition in plasma samples of colorectal cancer patients, revealing a significant increase in glycoprotein content for those with a poor prognosis. In summary, we have developed an innovative method for glycoprotein determination that shows potential for clinical translation.
