Knocking-Induced Vibration and Sound Signal Characteristics and Fractal Analysis for Distinguishing Concrete and Masonry Walls.

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
Accurately distinguishing between concrete walls and masonry walls in nondestructive testing of building structures is of crucial importance for structural maintenance and renovation. This study proposes a wall recognition method based on impact response and fractal theory: by collecting sound and vibration signals excited by impact, it is found that there are significant differences between the two types of walls in terms of time-domain characteristics (peak duration of sound signals, vibration amplitude) and fractal characteristics (fractal dimension distribution, intercept of fitting line). Independent sample test results confirm that these differences are statistically highly significant (
