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
The paper investigates the impact of the height of the automotive radar mounting on the detection performance of vehicle active safety systems, with particular emphasis on multipath interference. Multipath occurs when radar signals are reflected by surfaces such as road pavement, leading to signal oscillations, false detections, or temporary loss of target tracking, which can degrade the reliability of active safety functions. The controlled experiments were conducted using mid- and long-range radar sensors mounted at heights ranging from 20 to 120 cm. Standardized targets, including pedestrian dummies, a Global Vehicle Target, and a corner reflector, were used. Straight-line approach scenarios at 30 km/h on a 250 m test track were evaluated using detection filtering and Radar Cross-Section analysis. The results demonstrate that low mounting heights (20-40 cm) significantly intensify multipath effects, whereas higher mounting positions (100-120 cm) reduce the detectability of low-profile obstacles. The best overall performance across the evaluated sensors in the controlled straight-line test scenario was achieved within the 40-100 cm mounting-height range, providing a good balance of detection reliability for both vehicles and pedestrians.
