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
backgroundOrthodontic tooth movement involves osteogenesis of periodontal ligament stem cells (PDLSCs) in response to tension force. Piezo1 was recognized as a mechanically sensitive channel in 2010, capable of activation by tension force. However, its specific role in tension-induced osteogenic differentiation of PDLSCs remains unclear. This study aims to investigate the involvement Piezo1 in this process.
methodsHuman PDLSCs were cultured and characterized. Following exposure to half-sine periodic tensile stress (0.1 Hz, 12% elongation) for durations of 0, 1, 3, 6, 9, and 12 h using a Flexcell tension system, phalloidin staining and CCK-8 assays were used to assess the actin cytoskeleton and cell viability, respectively, of PDLSCs. The expression levels of Piezo1 and Ca2+/calmodulin -dependent protein kinase (CaMKII), as well as CaMKII phosphorylation and calcium influx were evaluated in PDLSCs. The osteogenic factors expression levels (Runt-related transcription factor 2 [Runx2] and alkaline phosphatase [ALP]), together with ALP staining and measurement of ALP activity, were evaluated to characterize osteogenic potential of PDLSCs. Besides, the levels of Yes-associated protein (YAP), and β-catenin as mechanosensitive signaling molecules were also assessed.
resultsAfter application of the tension force, the PDLSCs exhibited a more extensive spreading morphology, while there were no significant differences in cell viability among the 0, 1, 3, 6, 9, and 12 h groups. PDLSCs exhibited increased osteogenic potential, shown by upregulation of Runx2 and ALP and increased ALP activity after tension force application. Increased expression of Piezo1, accompanied by elevated calcium influx and enhanced CaMKII expression and phosphorylation, was observed in the stretched PDLSCs. The levels of the mechanosensitive signaling molecules YAP and β-catenin also increased in response to the tension force.
conclusionsTension force promotes Piezo1 expression and osteogenic differentiation in PDLSCs. It also enhances calcium influx, CaMKII expression and phosphorylation, and the expression of YAP and β-catenin. Piezo1 participate in the osteogenic differentiation of hPDLSCs under tension force, providing new insights into the molecular mechanisms of osteogenic differentiation in PDLSCs and suggest potential therapeutic targets for modulating bone remodeling during orthodontic tooth movement.
