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
Purpose: Reliable gait analysis is essential for clinical assessment and research. Wearable technologies such as the WalkinSense system (WSS), a wireless instrumented insole system equipped with an inertial measurement unit, enable the measurement of spatiotemporal and kinematic gait parameters in real-world settings. The accuracy of the WSS has been previously validated. This study aims to evaluate the test-retest reliability of the WSS in healthy adults walking and running under various speed and slope conditions. Methods: Forty-nine healthy adults completed two sessions one week apart, walking and running at 3, 4.5 (-3°, -6°, +3°, +6°), 6 and 9 km/h on a treadmill. Spatiotemporal variables, including stance time, swing time, stride time, stride length, single and double support time, as well as kinematic variables such as foot ground angle at initial contact and toe-off, were recorded using the WSS. Relative reliability was assessed using intraclass correlation coefficients (ICC Results: Results demonstrated good to excellent reliability for most spatiotemporal parameters across all conditions, with ICC values ranging from 0.76-0.95, while the foot ground angles exhibited lower reliability (ICC: 0.71-0.86). SEM% and MDC% were generally below 10% for spatiotemporal measures (SEM%: 1.63-6.63; MDC%: 3.44-18.36), reflecting both low measurement error and high sensitivity to detect real changes beyond random variation. Bland-Altman analyses revealed no relevant heteroscedasticity. Conclusion: These findings support the WSS as a reliable tool for assessing spatiotemporal variables in healthy adults across diverse walking and running conditions, underscoring its potential for use in both clinical and research environments. However, clinical studies are needed to fully establish its utility in patient assessment. Level of Evidence: Level II, diagnostic studies.
