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
Background and Purpose: Diabetic wounds are serious chronic complications of diabetes and can lead to amputation and death. Although considerable progress has been made in drugs and materials for treating it, it's still an urgent clinical problem as the materials and drugs have potential therapeutic drawbacks, such as low delivery efficiency and poor tissue permeability. To promote diabetic wound healing, a composite of thonningianin A (TA)-loaded chitosan nanoparticles (CNPS) encapsulated by a Pluronic F-127 (PF-127) hydrogel (TA-CNPS-PF) was developed in this study. Methods: TA-CNPS was prepared by ionic gelation method and TA-CNPS was thoroughly dispersed into PF-127 hydrogel to prepare TA-CNPS-PF. The particle size, hydrogel structure, encapsulation ratio, release ratio, antimicrobial properties of TA-CNPS-PF were determined and the effect of TA-CNPS-PF on diabetic wounds was assessed. The effect of TA on macrophage polarization was also examined in vitro. Results: The particle size was approximately 100 nm of TA-CNPS-PF and the hydrogel had a homogeneous three-dimensional reticulation structure. The encapsulation efficiency of TA in the CNPS were 99.3% and the release ratio of TA-CNPS-PF was approximately 86% and has antimicrobial properties. TA-CNPS-PF promoted diabetic wound healing significantly. Histopathology confirmed that TA-CNPS-PF promoted complete re-epithelialization and adequate collagen deposition. TA promoted the polarization of M1 macrophages into M2 macrophages via light microscopy, immunocytometry and flow cytometry. TA-CNPS-PF also promoted an increase in the number of M2 macrophages in diabetic wounds. Conclusion: TA promotes diabetic wound healing by promoting the polarization of M1 macrophages into M2 macrophages and TA-CNPS-PF has good antimicrobial activity and a good drug release ratio in this study, which provides a new direction for the treatment of diabetic wounds and is expected to be highly advantageous in clinical diabetes wound therapy.
