Nonlinear Wave Mixing Approach for Internal Damage Localization in Concrete.

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
Nonlinear acoustics has emerged as a sensitive and promising non-destructive approach to damage detection in concrete structures. This study proposes a method based on nonlinear acoustics that uses collinear mixing ultrasonic waves to detect and locate defects (microcracks, macrocracks, spalling) in concrete. The method consists of analyzing the interaction between a low-frequency pump wave and a high-frequency probe wave, both travelling along the width of the block in opposite directions. This interaction produces a measurable time-of-flight shift in the probe wave, which accumulates along the sampling path. A nonlinear parameter (NL), defined as the spatial gradient of the normalized time shift, is introduced to suppress cumulative propagation effects and improve damage localization. The proposed technique is tested to detect and locate a thermally damaged concrete prism (0.25 × 0.08 × 0.15 m
