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
Objectives: In the present study, we evaluated the effect of a nanofibrous scaffold including polycaprolactone (PCL), chitosan (CHT), and bentonite nanoparticles (Ben-NPS) on wound healing in order to introduce a novel dressing for burn wounds. Materials and Methods: PCL, PCL/CHT, and PCL/CHT/Ben-NPS nanofibrous scaffolds were fabricated by the electrospinning technique. Their structural and physiochemical characteristics were investigated by Fourier-transform infrared spectroscopy (FTIR) analysis, scanning electron microscopy (SEM), tensile strength, water contact angle, as well as, swelling and degradation profiles test. The disc diffusion assay was carried out to investigate the antibacterial potential of the scaffolds. In addition, the cell viability and proliferation ability of human dermal fibroblasts (HDFs) on the scaffolds were assessed using MTT assay as well as SEM imaging. The wound-healing property of the nanofibrous scaffolds was evaluated by histopathological investigations during 3,7, and 14 days in a rat model of burn wounds. Results: SEM showed that all scaffolds had three-dimensional, beadles-integrated structures. Adding Ben-NPS into the PCL/CHT polymeric composite significantly enhanced the mechanical, swelling, and antibacterial properties. HDFs had the most cell viability and proliferation values on the PCL/CHT/Ben-NPS scaffold. Histopathological evaluation in the rat model revealed that dressing animal wounds with the PCL/CHT/Ben-NPS scaffold promotes wound healing. Conclusion: The PCL/CHT/Ben-NPS scaffold has promising regenerative properties for accelerating skin wound healing.
