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
The tomato leaf miner, Tuta absoluta, is a devastating pest that causes severe yield losses in tomato cultivation, threatening food security (SDG 2: Zero Hunger). Reliance on chemical insecticides has led to resistance development and environmental concerns, highlighting the need for sustainable pest management strategies that promote responsible consumption and production (SDG 12). In this context, the present study focused on the green synthesis of silver nanoparticles (AgNPs) using hexane extracts of Annona squamosa seeds and evaluated their potential as an eco-friendly insecticidal agent. The synthesized AgNPs were characterized physiochemically and structurally using UV–Vis spectroscopy, FTIR, XRD, EDX, and SEM analyses. The UV–Vis spectrum confirmed nanoparticle formation; FTIR analysis identified functional groups responsible for reduction and stabilization; XRD revealed the crystalline nature; and SEM/EDX showed spherical morphology with elemental silver signals. Insecticidal bioassays against T. absoluta demonstrated significant larval mortality of up to 96.66% within 48 h at 90 ppm. Biochemical assays revealed alterations in detoxification enzymes, with catalase (CAT) and glutathione S-transferase (GST) showing enhanced activity after 24 h of exposure, suggesting oxidative stress induction and enzyme modulation. Safety evaluation on the non-target organism Eudrilus eugeniae revealed low toxicity of 8.33% after 24 h when treated with nanoparticles synthesized from the hexane extract, highlighting environmental safety and supporting life on land and biodiversity conservation (SDG 15). Furthermore, molecular docking studies indicated strong binding affinities of bioactive phytochemicals from A. squamosa with key insect enzyme targets, such as acetylcholinesterase (AChE), supporting their role in nanoparticle-mediated toxicity. This study demonstrates the insecticidal efficacy and mode of action of A. squamosa-derived AgNPs. The findings support their potential as safe, sustainable nano-pesticides for managing T. absoluta, contributing to sustainable agriculture (SDG 2), promoting innovative, eco-friendly technologies (SDG 9), and fostering environmental sustainability (SDG 12, 15).
