1 · What the graph read from it

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.

2 · The registry

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

Bacterial outer membrane vesicles (OMVs) are emerging as promising platforms for drug delivery and immunotherapy. However, bacteria only secrete a small amount of OMVs during the growth process, which seriously restricts their large-scale application. Here, a series of high-yield OMVs mutants is developed based on probiotic Escherichia coli Nissle 1917 (EcN). The mutant strain (EcNΔtolRΔmlaE) with the highest OMVs yield reported so far is identified and characterized, and its OMVs yield is 180.8 times that of the wild-type strain. More importantly, a high-yield OMVs mutant (EcNΔtolAΔnlpI) that derived OMVs can significantly improve the secretion efficiency of exogenous proteins is screened and engineered for enhanced scalability and versatility. Leveraging this platform, the prepared TOB-PslG-mOMVs nanoantibiotics, co-delivering glycosyl hydrolase (PslG) and tobramycin (TOB), synergistically disrupt biofilms and demonstrate potent antibacterial effects against Pseudomonas aeruginosa. Additionally, the prepared FI-mOMVs nanovaccines displaying the OprF
