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
A double-coated Ti13Nb13Zr alloy was created by arc micro-oxidation (MAO) and subsequent electrophoretic deposition (EPD). The MAO ceramic was enriched with zinc ions, while the EPD-deposited chitosan coating contained silver nanoparticles. Both elements are important for the potential medical applications of the carved base material. To investigate the effects of the modification, morphological imaging by SEM, and spectroscopy analysis like EDS, XPS, and FTIR were performed. In addition, surface roughness, immersion, and wettability tests were carried out. Fabricated samples were also subjected to porosity, microhardness, and corrosion examination. The tests indicated that the MAO modifications carried out yielded a ceramic layer free of defects, while the most porous layer was found to be the one with a processing time of 10 min (MAO10). EPD coatings allowed the MAO pores to be covered, which did not reduce the surface roughness. Chemical bonding and composition studies confirmed the presence of Zn and Ag ions for each of the MAO and MAO_EPD modifications, with the XPS study showing these elements to be in oxide form. Roughness tests showed that the presence of the EPD coating generates increased standard deviations, which may be indicative of an irregular modified area, while a wetting test showed that each modified surface is hydrophilic and the MAO_EPD samples exhibit higher contact angle values than the single MAO modification. Corrosion resistance tests did not reveal a significant improvement compared to the native material; however, the obtained values are satisfactory for medical applications. All E
