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
backgroundOsteoporotic vertebral fracture (OVF) is an extremely common fragile fracture in the elderly population.
aimsTo explore the expression changes, clinical significance and mechanism of action of miR-148a-3p in the postoperative healing process of patients with OVF.
methods185 OVF patients who received percutaneous vertebroplasty (PVP) treatment were selected as the research subjects. RT-qPCR was used to detect the expression levels of miR-148a-3p and genes. ROC curve analysis was applied to evaluate the relationship between miR-148a-3p and postoperative healing, as well as its diagnostic value for delayed healing. In vitro, miR-148a-3p overexpression and knockdown cell models were established to investigate its potential mechanism in fracture healing.
resultsSerum miR-148a-3p expression in OVF patients was significantly higher than in healthy controls, and it gradually decreased over time after surgery. The expression of miR-148a-3p in the delayed healing group is significantly higher than that in the healing group, and it showed potential diagnostic value for delayed healing (AUC = 0.859). In addition, miR-148a-3p is an independent risk factor for delayed healing. In cell experiments, during the process of osteogenic induction, expression of miR-148a-3p decreased, while the expression of osteogenic markers increased. Mechanistically, miR-148a-3p directly targeted and inhibited MAFB expression; its upregulation suppressed cell proliferation and osteogenic marker expression, and these inhibitory effects were reversed by MAFB overexpression.
conclusionsmiR-148a-3p inhibits osteoblast proliferation and differentiation by targeting and suppressing MAFB, participates in the post-OVF healing process.
