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
This study aimed to evaluate the potential of zinc oxide nanoparticles (ZnO NPs) in the biofortification of lentil seedlings and subsequently improve the Zn status in rats. In the first phase of the study, the effects of various ZnO NPs concentrations (0, 10, 20, 40, 80, and 160 ppm) on the lentil growth, Zn accumulation, and other physiological parameters were investigated. Subsequently, the rats were fed ZnO NP-biofortified lentil seedlings (20 and 160 ppm) to assess their impact on animal health and Zn status. The results highlighted a concentration-dependent response of lentil seedlings to ZnO NPs, with optimal growth observed at 20 ppm, whereas higher concentrations inhibited lentil growth. Pigment and biochemical analyses revealed a complex interplay between chlorophyll, carotenoids, soluble sugars, and proteins with distinct responses to nanoparticle concentrations. Elevated levels of hydrogen peroxide and malondialdehyde of lentil seedlings at high concentrations of ZnO NPs suggest oxidative stress, countered by the upregulation of antioxidant enzymes and increased phenolic compounds. On the other hand. animal studies have showed that ZnO NP-biofortified lentil seedlings enhance serum zinc and magnesium levels in rats without affecting body weight. While serum triglyceride levels of rats decreased in both treatment groups, an elevation in creatinine and a marked increase in aspartate aminotransferase (AST) levels were observed at a higher ZnO NP concentration (160 ppm), indicative of potential kidney and liver stress. Paradoxically, serum iron levels were lower in all groups consuming lentil seedlings than in the control group, suggesting a potential interaction between lentil components and iron metabolism. These findings suggest that ZnO NP-biofortified lentils may be a promising approach to enhance Zn nutrition; however, further investigation is needed to optimize ZnO NPs concentration and assess long-term safety.
