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 investigates the potential of Cicer arietinum extract (CAE) as a cost-effective and environmentally friendly solution to prevent aluminum (Al) corrosion in acidic environments. This study aimed to identify a cost-effective and environmentally friendly corrosion inhibitor for aluminum. The effectiveness of CAE as a novel and environmentally safe inhibiting aluminum corrosion in a 1 M hydrochloric acid solution was evaluated using weight loss measurements (WL), potentiodynamic polarization (PDP), and electrochemical impedance spectroscopy (EIS). The surface morphology of Al that was corroded in the test solution was further investigated using atomic force microscopy (AFM) and scanning electron microscopy (SEM). Analysis of inhibition efficiency and kinetic data revealed the adsorption mechanism and isotherm type. The advantages of CAE include its non-toxicity, environmental friendliness, ease of preparation, and contain (O, P, and π-Bonds). The experiments showed that adding 150 ppm of CAE at 298 K resulted in an inhibition efficiency of approximately 91.1%. While increasing inhibitor concentration improved protection efficiency, higher temperatures reduced its effectiveness. The calculated low negative values of Gibbs free energy of adsorption (ΔG
