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

backgroundThis study integrates topology optimization, scalar field fusion (a method to realize smooth transition between solid and porous regions through implicit function interpolation), and directional porous structure control to develop a design method for customized metamaterial femoral prostheses, addressing key problems of conventional prostheses including poor implant compatibility, excessive bone resection, and insufficient long-term stability.

resultsWe initially completed the personalized design of femoral prostheses using a combination of retrograde and antegrade methods. This was followed by integrating topology optimization with porous structure filling to design the metamaterial. The prostheses were directly manufactured using 3D printing technology, and their performance was thoroughly evaluated. The results showed that the femoral prosthesis experienced the highest stress at 70° knee flexion (half-squat position), with a maximum stress of 1.269 ×

conclusionsAfter post-processing, the developed prototype serves as a valid proof-of-concept, thus establishing a foundation for the subsequent development and practical application of high-performance personalized biofix femoral prostheses.
