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

Addressing the needs of patients with lower-limb amputations remains a complex challenge due to the unique biomechanical and personal requirements of each individual. An effective prosthesis must be carefully adapted to ensure optimal comfort, flexibility, and stability. This study presents a finite element analysis aimed at developing an optimal implant model evaluated during lower-limb locomotion, specifically under two scenarios: normal walking and stumbling. The stumbling phase presents increased biomechanical demands, requiring greater balance and structural resilience. The analysis focuses on the influence of varying the liner's Young's modulus on the distribution of equivalent Von Mises stresses in the femur and implant. Additionally, the study investigates contact pressure and longitudinal shear stress distributions on the liner, providing a comprehensive comparison across all cases. The findings contribute valuable insights toward the optimization of prosthetic design for improved comfort and safety in everyday movement.
