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
purposeWe have developed and tested a novel conjugation of the clinically used prodrug aminolevulinic acid with 2-deoxyglucosamine as a novel probe (ALA-2DG) for fluorescence imaging and photodynamic therapy. PROCEDURES: ALA-2DG was successfully synthesized, and the mechanisms of probe uptake, PpIX synthesis, and photodynamic therapy efficacy were evaluated in vitro and in vivo.
resultsALA-2DG led to PpIX synthesis in tumor cells in vitro and in tumor in vivo. Competitive and inhibitory assays in vitro showed a reduction of this PpIX synthesis that was not observed when cells were incubated with ALA itself, indicating that intracellular uptake of ALA-2DG occurs by GLUT-mediated active transport. Initial photodynamic therapy studies confirmed the efficacy of ALA-2DG as a photodynamic sensitizer.
conclusionsThe in vitro assays suggest that ALA-2DG is taken up by cells via glucose transporters. Initial studies in oral cancer demonstrated the applicability of ALA-2DG for in vivo imaging and its potential as an alternative to ALA-PpIX-based fluorescence diagnostics and photodynamic therapy, providing higher tumor specificity.
