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
objectiveBoron neutron capture therapy (BNCT) is limited by inadequate boron delivery to tumor cells and the inability to visualize boron agents for personalized treatment. This study introduces DOTA-BPA-Gd, a dual-function boron agent integrating BNCT efficacy with drug tracing.
methodsDOTA-BPA-Gd was designed with four phenylboronic acid groups to target sialic acid residues on cancer cell surfaces. This strategy aims to enhance tumor boron accumulation while avoiding LAT1-mediated exocytosis and transporter saturation associated with BPA-F. With a molecular weight of ~ 1200 Da, DOTA-BPA-Gd allows efficient spatial binding to sialic acid, improving targeting specificity. Cellular uptake, cytotoxicity, and boron distribution were evaluated, followed by in vivo BNCT experiments with MRI monitoring.
resultsDOTA-BPA-Gd effectively delivered boron to cancer cells without detectable toxicity. Under neutron irradiation, the DOTA-BPA-Gd + N group showed significant tumor inhibition, with tumor volumes reduced to about one-third of those in the BPA-F + N group. Furthermore, gadolinium enabled real-time MRI-based tracking of boron biodistribution, confirming the agent's dual functionality.
conclusionsDOTA-BPA-Gd offers a promising strategy for BNCT by combining targeted boron delivery with non-invasive imaging. This integrated approach improves treatment precision, enhances therapeutic efficacy, and may help overcome key clinical challenges in BNCT.
