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: Cell membrane-derived nanovesicles, particularly those originating from red blood cells (RNVs), have garnered considerable attention as innovative drug delivery vehicles in oncology, owing to their exceptional biocompatibility, immune evasion, and prolonged systemic circulation. Nevertheless, their inherently poor tumor-targeting efficiency and nonspecific biodistribution present major obstacles to their therapeutic translation. Objectives: This study sought to functionalize RNVs with a diverse array of tumor-targeting ligands - cRGD, transferrin (TRF), folic acid (FA), GE11, and RVG29 - and to systematically compare their tumor-homing efficiency, biodistribution, and biosafety in a breast cancer model. Results: Functionalized RNVs exhibited markedly enhanced tumor affinity relative to unmodified vesicles in both Conclusion: This work presents systematic comparative evaluation of ligand-engineered RNVs, underscoring cRGD as the most potent targeting moiety for breast cancer. These findings illuminate critical design principles for the rational development of tumor-directed RNV-based drug delivery systems and strengthen the translational promise of biomimetic nanocarriers for clinical oncology.
