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
This study examines the deposition of chromium nitride (CrN) films on 304 stainless steel (304SS) substrates using radio-frequency (RF) magnetron sputtering, with RF power varied from 20 to 160 W in an argon atmosphere. The structural, topographical, and corrosion resistance properties of the films were analyzed using X-ray diffraction (XRD), atomic force microscopy (AFM), scanning electron microscopy (SEM), and electrochemical polarization measurements. Employing the atomic force microscope, morphological characteristics of CrN films under constant conditions using Minkowski Functionals were analyzed. Subsequently, by examining parameters like root-mean-square roughness, skewness, and kurtosis, the study revealed the variations in the particle distribution and their probability density as a function of deposition power alterations. Results indicate that increasing RF power enhances film crystallinity, as evidenced by intensified XRD peaks. With an increase in RF power reaching up to 80 W, there is a significant enhancement in the uniformity of the surface, resulting in an evenly spread grain pattern. Corrosion tests in 0.5 M sulfuric acid, assessed via potentiodynamic polarization, identify 80 W as the optimal RF power for maximizing corrosion resistance. This study provides insights into the relationship between film structure, surface characteristics, and corrosion behavior, highlighting key factors influencing protective performance.
