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
Non-contact ultrasonic three-dimensional (3D) printing has emerged as a promising alternative to conventional energy-curing manufacturing techniques. However, an insufficient understanding of its underlying curing mechanisms still limits the precise regulation of solidification behavior and stable structural forming. In this context, this work develops a customized ultrasonic printing platform to investigate the thermoacoustic curing behavior of a modified PDMS-based material system. A multiphysics numerical model is established to characterize the focal acoustic pressure, concentrated energy distribution, and transient temperature evolution during printing. Simulated and experimental results collectively indicate that solidification behavior is governed by the balance between localized acoustic energy confinement and thermal diffusion. Systematic experiments are further conducted to quantify the effects of driving power, scanning speed, and line spacing on forming quality. The optimized parameter combination (17.5 W driving power, 0.4 mm/s scanning speed, and 0.2-0.25 mm line spacing) enables stable single-track morphology and favorable interlayer bonding. Additionally, reciprocating scanning trajectories are found to promote localized thermal accumulation, which may introduce dimensional deviations in printed structures. This study provides insights into ultrasonic thermoacoustic curing behavior and offers feasible process guidance for ultrasonic additive manufacturing under the specific material and experimental configurations adopted in this work.
