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

This study aimed to evaluate the mechanical performance of CF/PEEK composite plates for external fixation through finite element analysis (FEA), and to explore the impact of different screw placement patterns on fixation stability. A proximal tibial fracture model treated with external fixation was constructed using FEA. Longitudinal loading was applied to simulate walking stress, with additional internal and external rotational torques to mimic load-bearing movement. Mechanical responses of titanium alloy and CF/PEEK plates were compared under three loading conditions: longitudinal, longitudinal with internal rotation, and longitudinal with external rotation. Screw alignment was also varied between linear and non-linear configurations to assess its biomechanical influence. Compared to titanium alloy group, the linear CF/PEEK plate exhibited a mild increase in displacement of 0.232-0.386 mm (8.23-11.14%), accompanied by a substantial reduction in plate stress of 46.03-80.84%. At the fracture site, interfragmentary displacement increased slightly by 0.105-0.132 mm (5.56-6.74%), while fracture-site stress increased by 3.119-18.029 MPa (18.30-63.20%). The non-linear CF/PEEK plate demonstrated a similar biomechanical performance, with no significant differences compared with the linear configuration. For external plate fixation, CF/PEEK represents a promising alternative to conventional titanium alloy plates. By allowing an acceptable level of local micromotion, CF/PEEK plates significantly reduce stress in the plate and screws while increasing stress transfer at the fracture site. This load-sharing behavior may mitigate stress shielding associated with traditional metallic plates and thereby promote early biological fracture healing.
