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
Zn-astrakanite/CuO/ZnO nanocomposite was prepared using environmentally friendly and biogenically derived approaches through nanoengineering. Tribulus terrestris plant extract was used in this study to synthesize the Zn-astrakanite/CuO/ZnO nanocomposite. For the first time, the formation of a Zn-substituted astrakanite structure was achieved using a green synthesis method guided by the reducing, capping, and chelating agents present in the Tribulus terrestris plant extract. By using Ultraviolet visible (UV-vis) spectroscopy, we observe a characteristic peak at 376 nm that indicates the presence of ZnO nanoparticles, and in addition, the appearance of green color confirmed the presence of CuO nanoparticles in colloidal solutions. An analysis of Rietveld refined powder X-ray diffraction (PXRD) provides insight into the novel crystalline structure of Zn-astrakanite. It was found from the Rietveld refinement results that the synthesized nanocomposite composed of CuO, Zn-astrakanite, and ZnO crystalline phases with compositions 56.26%, 31.49%, and 12.26%, respectively. The green color appearance of the synthesized nanocomposite in colloidal solution was due to the presence of CuO nanoparticles as a major composition and surface plasmon resonance (SPR) characteristic. As revealed by scanning electron microscopy (SEM) analysis, nanoparticles have blade-like morphologies due to ZnO and some randomly shaped crystallites. Fourier transform infrared spectroscopy (FTIR) analysis provides functional information about the synthesized compound, and we detected CuO and ZnO nanocomposites by observing the metal oxide fingerprint regions at 523 cm
