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
Silver nanoparticle solutions (AgNPs) of some mushrooms: Pleurotus ostreatus, Agaricus bisporus and Agaricus campestris were prepared and characterized using Transmission Electron Microscopy (TEM), Fourier-Transform Infrared (FTIR) spectroscopy, X-Ray Diffraction (XRD) analysis and Energy Dispersive X-ray (EDX) spectroscopy. Each of the myco-sythesized AgNPs was plated against strains of Aspergillus flavus and A. ochraceous, at 5, 10 and 15% concentrations. Colour change from light yellow to orange, yellowish-brown, and reddish brown was observed after overnight incubation (at 28 °C), in the P. ostreatus, A. bisporus, and A. campestris synthesized AgNPs respectively. TEM analysis showed a spherical shape with an average size of 15.25 to 45.85 nm, 9.22 to 52.60 nm and 10.24 to 17.66 nm in P. ostreatus, A. campestris and A. bisporus AgNPs respectively. EDX spectrum showed absorption peaks of silver in the ranges of 0.8-1.4 keV, 6.2-6.6 keV, and 0.8-1.2 keV, and XRD analysis confirmed the crystalline structure of the biosynthesized AgNPs, while FTIR results revealed O-H, N-H, C=O, and C=N as the prominent functional groups. Mycelial inhibitions against A. flavus strains D28AF and D42AF ranged between 43.86-52.73% and 33.83-57.07% respectively, and were not significantly different (P ≤ 0.05) from the standard (copper sulphate). Inhibitions produced against A. ochraceous strains AOD40 and AOD45 ranged between 34.64-52.36% and 37.43-53.56% respectively and also showed similar trend in relation to the standard. This study showed that the myco-synthesized AgNPs were effective against A. flavus and A. ochraceous infecting cocoa beans at storage. They however need to be further improved for future use in the control of cocoa beans pathogens.
