Power-Based Running Durability in Trained Runners: Preliminary Evidence of Speed-Adjusted Mechanical Drift as a Marker of Fatigue.

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
This study examined wearable-derived running power and biomechanical variables as indicators of durability during prolonged dual-intensity exercise in trained trail runners. Twelve trained trail runners completed a 216-min treadmill protocol of three repeated 72-min blocks (60 min steady-state running at 85% of lactate threshold speed plus a 12-min uphill time trial [+12% incline]), plus an unfatigued control trial. A foot-mounted running power metre (Stryd Next Gen, Stryd Inc., CO, USA; firmware version 2.1.32.1.1) continuously recorded power output, duty factor, ground contact time, form power, cadence, vertical oscillation and leg stiffness. Repeated-measures ANCOVA with running speed as a covariate compared biomechanical across time trials at a common, model-adjusted running speed. During the uphill time trials, duty factor, ground contact time, leg stiffness, vertical oscillation and form power changed significantly after controlling for speed (all p < 0.05; η
