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
backgroundBone tissue engineering for alveolar clefts is in the early stages of development, and more research is needed to determine the optimal cell types, growth factors and delivery methods for the therapy.
methodsWe co-cultured Carbonic anhydrase 1 (CA1) induced dental follicle stem cells (DFSCs) with dental pulp stem cells (DPSCs). In vitro, the Lentivirus vector overexpressing CA1 (LV-CA1) gene was constructed, transfected into DFSCs, and co-cultured with DPSCs indirectly. Osteoblast biomarkers in differentiated DFSCs were detected using quantitative real-time polymerase chain reaction and Western blotting. In vivo, establish a rat alveolar cleft model, transplanted stem cell Polycaprolactone/β-tricalcium phosphate (PCL/β-TCP) three-dimensional printed composite scaffold and samples were collected at 4 and 8 weeks postoperatively. The osteogenic effect was evaluated through micro computed tomography and histomorphometric analysis.
resultsIn vitro, the activity of DFSCs in the LV-CA1+Co-culture group was increased, and the mRNA and protein expressions of CA1, Alkaline phosphatase (ALP), Bone morphogenetic proteins 2 (BMP2), and Runt-related transcription factor 2 (RUNX2) were amplified to varying degrees (P < 0.05). In vivo, micro-CT displayed at 4 and 8 weeks postoperatively, the LV-CA1+Co-culture group had a considerably higher percentage of new bone development (39.1% and 56.9%) (P < 0.05) than the other two groups. Histomorphometric analysis displayed the LV-CA1+Co-culture group had more newly formed bone trabeculae and immature collagen.
conclusionA strategy based on a novel osteogenic gene CA1 and dental-derived mesenchymal stem cells co-culture is applied to the alveolar cleft, providing a novel idea for the application of bone tissue engineering in alveolar cleft bone grafting.
