Effects of running speed on the probability of meniscal failure in the knee joint: based on finite element analysis and the Weibull failure model.

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
purposeThis study aims to develop a computational model to assess the cumulative probability of meniscal failure in the knee joint during running.
methodsThe knee joint forces of twelve male participants were measured while running at speeds of 9 km/h, 12 km/h, and 15 km/h. These forces were used as boundary conditions in a finite element model. The proportion of high-stress elements in the meniscus during the support phase was calculated, and a Weibull distribution-based failure model was used to compute the cumulative injury probabilities of the meniscus over 360 days at the three running speeds.
resultsRunning speed had a significant main effect on this ratio(p = 0.041, F = 3.393, η
conclusionsFaster running speeds result in higher knee joint reaction forces, however, the probability of meniscal failure is lower. The risk of meniscal failure is more strongly associated with the frequency of stress applications than with the magnitude of the stress itself. Slower running speeds require more gait cycles to complete the same running distance, thereby prolonging loading duration and increasing the number of stress applications.
