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
Lamellar graphite pearlitic grey cast irons are frequently used in the manufacturing of components that operate under cavitation erosion conditions. Their poor performance regarding cavitation erosion limits their use in intense cavitation environments. The physical modification of the surface layer offers a flexible and cost-effective way to combat cavitation attacks without altering the core properties. This paper comparatively analyzes the effects of four technological processing methods on the cavitation erosion resistance of grey cast irons. Cavitation erosion tests were conducted on a vibrating device with piezoceramic crystals in accordance with the ASTM G32-2016 standard. Surface hardness tests were carried out using a Vickers hardness tester, while roughness measurements were performed using a Mitutoyo device. The microstructures generated by the applied technologies and the surface wear mechanisms were analyzed using optical microscopy and scanning electron microscopy (SEM). The results indicated that the TIG local surface remelting process provides the most significant improvement in cavitation erosion resistance.
