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
Plant-based corrosion inhibitors can reduce electrochemical corrosion and environmental impact. This study evaluates the corrosion inhibition performance of jackfruit resin extract (JRE) for carbon steel in a 1 M HCl environment. The composition analysis of JRE by ATR-FTIR and LC-QTOF-MS showed that this extract contained many polar organic compounds and fatty acids, which act as surfactants facilitating the formation of a protective film on the steel surface. Electrochemical analyses confirmed the formation of a self-assembled protective film with high inhibition efficiency, which decreased with increasing temperature. Based on these analyses, JRE is demonstrated to be a mixed-type inhibitor with high performance at 3000 ppm concentration. Specifically, this extract can effectively achieved of 93.14 ± 0.25% at 25 °C and 83.11 ± 0.58% at 35 °C. Furthermore, surface analysis by SEM/EDS mapping and XPS confirmed that the compounds from the extract adsorbed onto the metal surface to form a uniform protective film. Generally, this study shows that JRE acts as an eco-friendly corrosion inhibitor with high efficiency and shows potential for application in industrial corrosion protection systems.
