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
backgroundIn tooth development, the Wnt/β-catenin pathway has been shown to play a crucial role in tooth germ formation and tooth differentiation. Regeneration can be considered a replay of development. Understanding and reproducing the involvement of Wnt10a-which is reported to be the causative gene for congenital multiple tooth absence and participates in tooth development with spatiotemporal specificity-in pulp regeneration is essential for realizing dental regenerative medicine. Therefore, this study was initiated based on the concept that evaluating the dynamics of Wnt10a during angiogenesis, which is thought to occur early in dental pulp regeneration, could contribute to a more detailed elucidation of the dental pulp regeneration mechanism.
methodsDeciduous dental pulp stem cells (SHED) were isolated from human deciduous teeth, and conditioned medium (CM) was collected. In addition, after the induction of vascular differentiation of SHED, the temporal gene expression of Wnt10a, VEGF-A, Tie-2, and β-catenin was analyzed by q-PCR and protein expression by Western blotting and ELISA from 0 to 48 h and 3, 7, 14, and 21 days after the induction.
resultsCanonical Wnt signaling was activated during angiogenesis in regenerated pulp-like tissue induced by ectopic root grafting, and Wnt10a had spatio-temporal specificity. Tie-2 activation occurred during the process of induction of vascular differentiation in SHED.
conclusionsDuring angiogenesis in pulp regeneration, when SHED differentiate into blood vessels, Canonical Wnt signaling and VEGF-A are activated to form microvessels, and Tie-2 expression is enhanced to increase vessel circumference. Furthermore, Wnt10a was found to be activated in its early stages and decreased in its mature stages, with spatio-temporal specificity. Because its expression is very low, Wnt10a could be a biomarker to monitor the regenerative status of pulp regeneration.
