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

Many age-related gait changes (i.e., shorter steps, slower speeds, higher metabolic rate, instability) may be precipitated at least in part by reduced push-off intensity and a diminished ability to regulate foot-ankle leverage during walking. Carbon fiber insoles (CFIs) have been shown to improve foot-ankle leverage in younger and older adults in group average comparisons. The purpose of this study in n = 20 younger adults and n = 20 older adults was to determine whether the efficacy of CFIs to enhance foot-ankle leverage during walking depends on passive structural midfoot mobility, measured here using the sit-to-stand navicular drop test (NDT). We hypothesized that greater NDT values, indicative of greater passive midfoot mobility, would correlate with greater increases in foot-ankle leverage when walking with CFIs versus standardized footwear. We defined the change in foot-ankle leverage using that of the peak external moment arm of the ground reaction force (ΔR
