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

Biomaterial-associated thrombus formation and bacterial infection remain major challenges for blood-contacting devices. For decades, titanium-based implants have been largely used for different medical applications. However, titanium can neither suppress blood coagulation, nor prevent bacterial infections. To address these challenges, tanfloc/heparin polyelectrolyte multilayers on titania nanotubes array surfaces (NT) were developed. The surfaces were characterized by scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), and water contact angle measurements. To evaluate the hemocompatibility of the surfaces, fibrinogen adsorption, Factor XII activation, and platelet adhesion and activation were analyzed. The antibacterial activity was investigated against Gram-negative P. aeruginosa and Gram-positive S. aureus. Bacterial adhesion and morphology, as well as biofilm formation, were analyzed using fluorescence microscopy and SEM. The anti-thrombogenic properties of the surfaces were demonstrated by significant decreases in fibrinogen adsorption, Factor XII activation, and platelet adhesion and activation. Modifying NT with tanfloc/heparin also reduces the adhesion and proliferation of P. aeruginosa and S. aureus bacteria after 24 hr of incubation, with no biofilm formation. The modified NT surfaces with tanfloc/heparin polyelectrolyte multilayers are a promising biomaterial for use on implant surfaces because of their enhanced blood biocompatibility and antibacterial properties.
