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
Objective: The aim of this descriptive study was to evaluate lower-limb biomechanical parameters in runners of different sexes and analyse how these parameters are modulated across three intensities (65%, 85% and 100% maximal aerobic speed [MAS]). Methods: One hundred recreational runners (50 women, 50 men) completed a 2000-m time trial to determine MAS, followed by three 2-min treadmill bouts at 65%, 85% and 100% MAS. Kinematic and mechanical variables were recorded using the RunScribe™ inertial measurement system, with sensors positioned bilaterally on the shoes and on the sacral region. Results: Linear mixed-effects models showed a significant main effect of speed condition for most biomechanical outcomes. As speed increased from 65% to 100% MAS, runners showed shorter contact time and greater flight time, stride length, step rate, braking Gs, peak vertical ground reaction force, loading rates, shock, total shock and max pronation velocity. A significant main effect of sex was observed for several variables: men showed higher BG, flight time, stride angle, stride length, peak vertical ground reaction force, leg spring stiffness, loading rates and max pronation velocity, whereas women showed longer contact time. Sex × speed interactions were significant only for shock, total shock and max pronation velocity, indicating that most speed-related adaptations occurred in a similar direction in men and women. Conclusions: These findings provide a descriptive characterisation of sex- and speed-related IMU-derived running mechanics in runners. Standardised treadmill testing across relative intensities may help characterise how lower-limb mechanics are modulated by sex and running speed. Because injury incidence, running economy, race performance and longitudinal adaptations were not assessed, braking- and impact-related variables should be interpreted as hypothesis-generating rather than as evidence of injury risk or performance.
