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

PEEK (polyetheretherketone) is a semi-crystalline thermoplastic polymer which, thanks to its excellent mechanical properties, chemical resistance, and high biocompatibility, is widely used in medicine, especially in biomedical engineering. The dynamic development of additive technologies, especially FFF (Fused Filament Fabrication), has enabled the production of personalized medical implants from PEEK, such as skull implants, dental implant components, and orthopedic implants like spine, knee and hip implants. Therefore, the aim of the study was to evaluate the polymer as an alternative material for orthopedic applications and to analyze the effect of annealing and soaking in PBS solution on its strength properties. Heat treatment improves the strength properties of the material. On the other hand, prolonged soaking in PBS solution, which simulates physiological conditions, can lead to changes in the interlayer bonds of the filament layers, which in turn affects the strength properties of the material.
