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
backgroundThe rapidly increasing applications of zinc oxide nanoparticles (ZnO NPs) in various industries have led to growing concerns about their damaging influence on human health. The present research was designed to determine the protective action of vitamins (Vits) A, C and E on the heart toxicity induced by ZnO NPs.
methodsFifty-four male Wistar rats were allocated into 9 groups of 6 and then exposed to ZnO NPs (200 mg/kg), water (Control1), olive oil (Control2), Vit A (1000 IU/kg), Vit C (200 mg/kg), Vit E (100 IU/kg) and three groups were co-treated with ZnO and one of the Vits A, C or E. The oxidative stress situation was evaluated by measuring oxidative stress markers and the tissue antioxidant enzyme activity. Besides, the mRNA expression of Bcl-2 and Bax and caspase 3,7 activity were assessed. A histopathological examination was also performed to determine the rate of cardiac injury.
resultsThe results indicated that co-administration of ZnO NPs and the aforementioned Vits significantly reduced the total oxidant status and lipid peroxidation relative to the ZnO group (P < 0.05). Furthermore, the supplementation of vitamins, notably Vit E, decreased the ZnO NPs-induced oxidative damage by enhancing the activity of antioxidant enzymes compared to the ZnO NPs-fed rats (P < 0.05). Data also showed the mitigating effects of Vits against ZnO NPs-mediated apoptosis by suppressing the ratio of Bax/Bcl-2 expression and caspase 3,7 activity.
conclusionThis study highlights the protective role of Vits A, C and E against ZnO NPs cardiotoxicity, though at different levels of effectiveness.
