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

The posterior horns of the medial menisci are more commonly injured during exercise. Cushioning insoles are one of the most widely used conservative interventions for preventing knee joint injuries. However, the effect of the cushion property of insoles on the knee joints with meniscal tears remain unknown. We investigated the effects of insoles with different cushioning properties on the knee joint following a radial tear of the posterior horn of the medial meniscus. Full extension landing with a heel-first strike pattern was performed by 12 participants randomly wearing ethylene vinyl acetate (EVA) and artificial cartilage foam (ACF) insoles, and the peak plantar pressures (pPP) were measured. The right knee of the participant whose pPP was closest to the median was loaded to a finite element model with radial tear. The pPP of EVA insoles (2386.42 ± 298.29 N) was higher than that of ACF (2174.16 ± 270.63 N) (t = 7.84, P < 0.001). The finite element analysis revealed that the peak von Mises Stress (pVMS) values of the medial and lateral menisci were 12.32 MPa and 7.90 MPa for injured joint with EVA, and 9.02 MPa and 6.84 MPa for injured joint with ACF. Hence, insoles with higher cushioning can decrease the vertical impact force and stress concentration of the knee joint after radial tear of the posterior horn of the medial meniscus.
