1 · What the graph read from it

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.

2 · The registry

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 green synthesis, characterization, and biological activities of iron oxide nanoparticles (IONPs) synthesized from clove and green coffee extracts. FTIR spectroscopy identified reactive functional sites, including -OH, C=O, and polyphenolics, confirming their role as reducing and stabilizing agents XRD analysis showed amorphous IONPs at ambient temperature and crystalline phases after annealing at 550 °C. SEM imaging revealed pyramidal morphologies for green coffee-derived IONPs and rod-like structures for clove-derived IONPs. Also, nitrogen adsorption and desorption (BET) and X-ray photoelectron spectroscopy were used to gain a thorough grasp of the surface characteristics of the nanoparticles. The Dubinin-Radushkevich isotherm best described caffeine adsorption, confirming physisorption, while the Langmuir model indicated monolayer adsorption with maximum capacities of 596.91 mg/g (clove) and 714.55 mg/g (green coffee). Kinetic studies suggested pseudo-second-order adsorption for green coffee-derived IONPs (R
