Influence of types of railway traffic on ground borne vibration towards vibration threshold limit.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Ground-borne vibration (GBV) presents critical challenges in urban environments when levels exceed residential thresholds. This study investigates the influence of train type, speed, distance, soil conditions, coach length, and ballast and embankment height on GBV. Findings reveal that high-speed trains operating at 80–160 km/h generated the highest PPVs, with most values surpassing the 0.8 mm/s DOE guideline even at 7 m. Commuter trains exhibited intermediate vibration levels, whereas LRT systems produced the lowest PPVs, largely within perceptibility limits. Vibrations attenuated with distance but were amplified in soft soils. The CART regression model identified train speed (100%) and distance (79.7%) as the dominant predictors, with strong predictive accuracy (R2 = 97.94% training; 97.75% testing). These results emphasise the need for effective GBV management strategies in dense urban settings.
