Tartrazine-enhanced visible-light OCT for deep-tissue imaging.
Article in Biomedical optics express, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Visible-light optical coherence tomography (vis-OCT) provides ultrahigh axial resolution and intrinsic spectroscopic contrast, but its performance in deep tissues is fundamentally limited by strong scattering and absorption at short wavelengths. Here, we report the use of tartrazine-an FDA-approved, water-soluble food dye-as a rapid, biocompatible contrast enhancer to improve vis-OCT penetration and structural visibility across multiple tissue types. We systematically evaluated tartrazine-assisted imaging in postmortem chicken muscle, optic nerve, and brain cortex, as well as
