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 reports the green synthesis of iron nanoparticles (FeNP-CC) using aqueous seed extract of Canavalia cathartica, a less explored mangrove associate, and evaluates their efficacy in the remediation of hexavalent chromium (Cr(VI)) from aqueous systems. Phytochemical and spectroscopic analyses using LC-MS/MS, UV-visible spectroscopy, FTIR, HR-TEM, and XRD confirmed that bioactive constituents such as polyphenols and L-canavanine acted as both reducing and stabilizing agents during the synthesis of FeNP-CC, resulting in nanoparticles with a nanocrystalline core-shell morphology. Adsorption experiments revealed that Cr(VI) removal followed pseudo-second-order kinetics, suggesting a chemisorption-dominated mechanism. Equilibrium studies fitted best to the Freundlich isotherm model (R
