Smoothness of gait in healthy older females and patients with postoperative proximal femur fracture.

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.
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
[Purpose] This study aimed to investigate the usefulness of a quality index in gait for proximal femur fractures. [Participants and Methods] In this study, 20 females with postoperative proximal femur fracture in the preparation phase for discharge (femur fracture group) aged ≥60 years (63.0 ± 3.0 years) and 20 healthy older females (healthy group) participated (75.7 ± 7.7 years) (n=40). Measurements were conducted at comfortable and maximal gait speeds. Power spectrum entropy (PSE), harmonic ratio (HR), and modified HR (mHR), which are smoothness indices, were calculated from the measured data in each of the three axial directions and compared. [Results] The healthy and femur fracture groups showed significant differences in the PSE, HR, and mHR for comfortable and maximal gait speed in the lateral and vertical directions. Furthermore, all directions between the HR and mHR in the femur fracture group had significant differences. [Conclusion] The usefulness of the PSE, HR, and mHR as quality evaluation indices of gait was demonstrated in patients with postoperative femur fractures after unilateral disability.
