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
There is a high demand for high performance, effective and eco-friendly corrosion inhibitors for industrial applications. Consequently, many researchers are focused on developing efficient, cost-effective materials to protect metals. In this study, an ecofriendly chitosan methionine derivative (M) was developed, synthesized, characterized, and tested for its anticorrosion properties. The ability of this compound as a corrosion inhibitor for carbon steel (CS) was confirmed through weight loss measurements (WL), potentiodynamic polarization (PDP), and electrochemical impedance spectroscopy (EIS) studies in a 1.0 M hydrochloric acid solution. The findings showed that the inhibitor, M, achieved a maximum inhibition efficiency of 99.8% at a concentration of 100 ppm by the PDP method. Additionally, the corrosion potential value, being less than 85 mV, supported classifying M as a mixed-type inhibitor with a cathodic tendency. The adsorption behavior of the inhibitor on the CS surface was consistent with Langmuir's adsorption isotherm. EIS data also confirmed that increasing inhibitor concentration raised the charge transfer resistance (R
