1 · What the graph read from it

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.

2 · The registry

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

Dental pulp extracellular matrix (DPEM), as a naturally derived scaffold material for dental pulp regeneration, exhibits excellent biocompatibility. This study aims to develop a novel photo-cross-linked hydrogel composed of methacry- lated gelatin (GelMA) loaded with DPEM for application in pulp regeneration. In vitro experiments demonstrated that the GelMA–DPEM hydrogel, fabricated by mixing a 10 mg mL − 1 DPEM solution with a 10% (w/v) GelMA solution at a ratio of 1:1, formed a stable cross-linked network with a swelling ratio of approx- imately 343%. Frequency-sweep rheology indicated that incorporation of DPEM increased the storage modulus of the hydrogel compared with GelMA alone, and the composite hydrogel significantly promoted cell migration and angiogenic ca- pacity. RT–qPCR analysis revealed that the GelMA–DPEM hydrogel markedly upregulated the expression levels of neuroepithelial stem cell protein (Nestin), dentin sialophosphoprotein (DSPP), platelet endothelial cell adhesion molecule-1 (CD31), and runt-related transcription factor 2 (Runx2). Moreover, ectopic trans- plantation in nude mice indicated that, when combined with human dental pulp stem cells (hDPSCs), the GelMA–DPEM hydrogel preserved the DPEM’s capa- bility to support the formation of a cell-rich, vascularized pulp-like tissue con- sisting of collagen-rich connective tissue and CD31-positive blood vessels. In conclusion, the GelMA–DPEM hydrogel showed favorable cytocompatibility and preliminary pro-angiogenic effects in vitro and supported pulp-like tissue forma- tion in a small-animal ectopic treated dentin matrix (TDM) model. These findings suggest that GelMA–DPEM is a promising candidate scaffold for dental pulp re- generation.
