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
The presence of gingival black triangles in the anterior dentition poses significant esthetic and functional concerns. Conventional surgical interventions, despite being the most widely employed techniques, are hampered by inherent invasiveness, technique sensitivity, and unpredictable regenerative outcomes. These limitations drive the need for effective and predictable non-surgical alternatives. Herein, we develop an injectable biomaterial through the self-assembly and self-crosslinking of activated plasma albumin gel (APAG) with concentrated growth factors (CGF), effectively encapsulating bioactive components within a stable network. The APAG/CGF biomaterial exhibits a hierarchical microstructure with uniform porosity and nanofibers, controlled biodegradability, and rich growth factors, collectively constituting a biomimetic microenvironment. Notably, this matrix enables the sustained release of growth factors, which enhance the viability, proliferation, and migration of human periodontal ligament stem cells (PDLSCs) for at least 14 days in vitro. In clinical application, the injection of APAG/CGF into anterior gingival black triangle regions successfully promotes excellent reconstruction of the gingival papillae, with outcomes maintained over a 6-month follow-up period. In conclusion, this study introduces an injectable APAG/CGF biomaterial as a promising non-surgical strategy for gingival black triangle reconstruction by leveraging a biomimetic microenvironment to potentiate essential cellular functions.
