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: Autogenous soft-tissue graft is the gold-standard approach to augment oral soft tissues. However, tissue engineering is increasingly surveyed to overcome its substantial drawbacks, including the secondary site of operation, patient's pain and discomfort, limited tissue of donor site, and so on. Chitosan and gelatin have been utilized in this field over the years due to their great biological virtues. Zeolite, another remarkable candidate for tissue engineering, possesses outstanding biological and mechanical properties, thanks to its nanostructure. Therefore, this study aimed to investigate the biodegradability and DNA content of seeded human gingival fibroblasts on a New Chitosan-Gelatin-Zeolite Scaffold for the perspective of oral and mucosal soft tissue augmentation. Materials and Methods: DNA contents of the human gingival fibroblast cell line (HGF.1) seeded on the chitosan-gelatin (CG) and CGZ scaffolds were evaluated by propidium iodide staining on days 1, 5, and 8. Scaffolds' biodegradations were investigated on days 1, 7, 14, 28, 42, and 60. Results: Although both scaffolds provided appropriate substrates for HGF.1 growth, significantly higher DNA contents were recorded for the CGZ scaffold. Among experimental groups, the highest mean value was recorded in the CGZ on day 8. CGZ showed a significantly lower biodegradation percentage at all time points. Conclusions: The incorporation of zeolite into the CG scaffold at a ratio of 1:10 improved the cell proliferation and stability of the composite scaffold. CGZ scaffold may offer a promising alternative to soft-tissue grafts due to its suitable biological features.
