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 objective of this research is to study the hydrodynamics and performance of piezoelectric PZT-5A patches in the context of turbulent fluid flow, with a specific focus on the impact of structural positioning on output performance. The numerical three-dimensional model consists of piezoelectric PZT-5A patches affixed to beams and positioned inside a uniform circular pipe. The modeling and simulation of the piezo-beams are conducted using ANSYS-Fluent software to analyze the vortex shedding phenomenon, which occurs due to induced vibrations from the interaction of the fluid with the PZT beams. A vorticity analysis is included to better understand the flow dynamics around the structures, revealing insights into the flow patterns that enhance energy harvesting. Additionally, a grid independence study is performed to ensure that the numerical results are reliable and not dependent on the grid resolution. This study confirmed that the results are consistent across different mesh densities, providing confidence in the accuracy of the simulations. The study also explores how turbulent flow increases the output voltage. It examines the effect of varying the spacing distance between two structures, considering three cases with distances of
