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

Orthopaedic implants require surfaces that resist bacterial colonisation while supporting host cell compatibility. In this study, we fabricated highly interconnected porous titanium (Ti) foams using a cost‑effective sintering-dissolution process (SDP) and functionalised them with 11‑aminoundecyltriethoxysilane (AUTES) and covalently tethered N-diazeniumdiolate nitric oxide (NO) donors. Structural characterisation by Scanning electron microscopy, X‑ray micro‑CT, and Brunauer-Emmett-Teller analyses confirmed a hierarchical porous architecture with ~ 73% total porosity and extensive internal surface area, enabling efficient chemical functionalisation. Chemiluminescence analysis demonstrated formulation‑dependent NO payloads and sustained release for over 15 h in bacterial culture medium. The NO‑releasing foams significantly reduced biofilm-associated Escherichia coli and Staphylococcus aureus compared with untreated controls, with the 20% AUTES/NO formulation showing the most persistent antibiofilm activity at 24 h (p < 0.05). Limited effects were observed against planktonic bacteria. Human mesenchymal stem cells (hMSCs) adhered to and remained viable on both unmodified and functionalised foams over 7 days, indicating cytocompatibility of the surface modification following NO release. These findings demonstrate that SDP-derived porous Ti foams can be functionalised for localised NO delivery and effective antibiofilm activity while maintaining initial hMSC compatibility, offering a scalable platform for multifunctional Ti-based implant surfaces.
