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

backgroundOvercoming bacterial biofilm barriers to enhance the efficacy of antibiotics remains a major therapeutic challenge, necessitating the development of efficient and biocompatible drug delivery systems. While framework nucleic acids (FNAs) have emerged as promising candidates for overcoming biological barriers, their biofilm penetration efficiency and mechanistic interactions require systematic exploration. This study evaluates the biofilm-penetrating capacity of FNAs with distinct topological configurations (linear, triangular, and tetrahedral), investigates their antibiotic delivery performance in biofilm-infected models, and elucidates the structure-dependent interactions between FNAs and bacteria.

resultsDNA tetrahedron (Td) demonstrated superior biofilm penetration, exhibiting 44-fold and 11-fold stronger fluorescence intensity at a biofilm depth of 20 μm compared to linear and triangular counterparts, respectively, while maintaining structural stability. The optimized polymyxin B-loaded Td (PMB@Td, with a PMB: Td ratio of 10:1) enhanced biofilm permeability by 6-fold relative to free PMB. PMB@Td outperformed conventional liposome-encapsulated PMB (PMB@Lipo), achieving half-maximal biofilm eradication concentrations (MBEC

conclusionsThis work establishes Td as a robust nanoplatform for overcoming biofilm-mediated antibiotic resistance. The topology-dependent interactions provide critical design principles for engineering next-generation nanocarriers against biofilm-associated chronic infections, with significant translational potential in antibiofilm therapy.
