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 reports the green synthesis of bioactive zinc oxide nanoparticles (MK-7 ZnO NPs) using Nostoc sp. strain MK-7 extract as a natural reducing and stabilizing agent. The formation of ZnO NPs was confirmed by UV-visible spectroscopy with a characteristic absorption peak at 312 nm. FTIR analysis revealed the involvement of bioactive functional groups (O-H, C = O, C-O, and Zn-O), indicating their role in nanoparticle reduction and stabilization. XRD analysis confirmed the crystalline nature of the nanoparticles with a prominent peak at 36.3°, and the average crystallite size was calculated to be 41.9 nm using the Debye-Scherrer equation. FESEM and TEM analyses demonstrated a well-defined hexagonal morphology, while EDS confirmed high zinc purity (82.3% by weight). Biological evaluations revealed that MK-7 ZnO NPs exhibited significantly enhanced bioactivity compared to the crude extract. The nanoparticles showed strong antioxidant activity, achieving 89.04% ABTS radical scavenging with an IC
