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
Introduction: Targeting tumor angiogenesis through vascular endothelial growth factor (VEGF) blockade represents a promising strategy for melanoma treatment. Here, we evaluate the therapeutic potential of HEBERSaVax, an anti-VEGF active immunotherapy, in aggressive B16-F10 syngeneic melanoma models. Methods: The antitumor activity of HEBERSaVax, formulated with aluminum phosphate adjuvant, was evaluated in C57BL/6 mice using two distinct B16-F10 melanoma models (i): subcutaneous inoculation to assess primary tumor growth inhibition, and (ii) intravenous inoculation to quantify lung metastasis suppression. Tumor vasculature and microenvironment changes were analyzed via immunohistochemistry (CD31, α-SMA, CD4, CD8). Results: HEBERSaVax significantly reduced primary tumor volume and weight in subcutaneous implants compared to adjuvant controls. Histopathological analysis revealed potent angiogenesis inhibition, decreased CD31 Discussion: Our results demonstrate that HEBERSaVax mediates dual antitumor efficacy by simultaneously suppressing VEGF-dependent angiogenesis and promoting immune-related changes in the melanoma microenvironment. These findings support the further development of HEBERSaVax as a promising active immunotherapy for VEGF-driven advanced melanoma.
