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
In this study, the corrosion behavior of hydroxyapatite (HA), hydroxyapatite-copper (HA-Cu), and hydroxyapatite-copper-collagen (HA-Cu-Col) nanocoatings electrochemically deposited on Ti-6Al-4V alloy was systematically investigated. For the hybrid coatings, collagen was incorporated via an immersion process followed by heat treatment at 80°C for 1 hour. Grazing incidence X-ray diffraction (GIXRD) confirmed the retention of the HA phase across all coatings, with Cu addition leading to co-precipitation of metallic Cu phases, evidenced by distinct peaks at 2θ angles of 34.3°, 42°, and 50.4°. Collagen integration, without forming new phases, resulted in a uniform organic-inorganic matrix and enhanced nanoscale porosity. Field-emission scanning electron microscopy (FE-SEM) revealed that the HA coating exhibited a dense needle-like morphology with lengths of 1-5 μm and rod diameters of 200-500 nm, whereas HA-Cu displayed a granular-floret structure interspersed with 20-50 nm copper nanoparticles. The hybrid HA-Cu-Col coating formed a compact fibrous-floret network with nanoscale uniformity. Tafel polarization tests indicated the highest corrosion potential (E
