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
Repairing critical bone defects remains a formidable challenge in regenerative medicine. Scaffolds that can fill defects and facilitate bone regeneration have garnered considerable attention. However, scaffolds struggle to provide an ideal microenvironment for cell growth and differentiation at the interior of the bone defect sites. The scaffold's structure must meet specific requirements to support endogenous bone regeneration. Here, we introduce a novel 3D-printed nanocolloidal gelatin methacryloyl (GelMA) hydrogel, namely, the nG hydrogel, that was derived from the self-assembly of GelMA in the presence of Pluronics F68, emphasizing its osteoinductive capability conferred solely by the specific nanocolloidal structure. The nG hydrogel, exhibiting remarkable pore connectivity and cell-adaptable microscopic structure, induced the infiltration and migration of rat bone mesenchymal stem cells (rBMSCs) into the hydrogel with a large spreading area in vitro. Moreover, the nG hydrogel with interconnected nanospheres promoted the osteogenic differentiation of rBMSCs, leading to up-regulated expression of ALP, RUNX2, COL-1, and OCN, as well as augmented formation of calcium nodules. In the critical-sized rat calvarial defect model, the nG hydrogel demonstrated improved repair of bone defects, with enhanced recruitment of endogenous CD29
