Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 work presents a new and efficient biobased hybrid hinge based on lanthanum (La) cations and trigonella grandiflora (TG) extract, represented as La@TG, in a 3.5% NaCl solution, as an organic/inorganic mild steel corrosion inhibitor. The concentration of La cations and TG components released into the solution at various pH levels was assessed using UV-Vis/ICP-OES analysis. The composition and morphology of the adsorbed film were characterized using analytical techniques such as atomic force microscopy (AFM), Fourier-transform infrared spectroscopy (FTIR), energy-dispersive spectroscopy combined with scanning electron microscopy (SEM-EDS), and grazing incidence X-ray diffraction (GI-XRD) on the submerged electrode. Electrochemical techniques were leveraged to examine the effectiveness of the La@TG hybrid and to understand its inhibition mechanism in both solution and coating (intact and scratched) phases. The electrochemical analyses in the solution phase revealed that the La@TG hybrid exhibits relatively good corrosion resistance. Additionally, in the presence of an artificial flaw, the epoxy coating containing the La@TG hybrid showed strong active/barrier protection with self-healing qualities.
