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
backgroundThe clinical diagnosis of delayed fracture healing currently lacks molecular markers that exhibit both high sensitivity and robust dynamic detection capabilities. To evaluate the value of lncRNA NEAT1 for diagnosing delayed fracture healing and its potential mechanism of action.
methods122 traumatic fractures patients were collected, including 61 normal fracture healing (NFH) patients and 61 delayed fracture healing (DFH) patients. LncRNA NEAT1 and miR-654-3p and osteoblast differentiation marker genes expression levels were examined using RT-qPCR. ROC curves and logistic analysis were used to assess lncRNA NEAT1 diagnostic value. CCK-8 method was used to detect the cell activity of osteogenic differentiated cells. Levels of apoptosis in osteogenic differentiated cells detected by flow cytometry. Relationship between lncRNA NEAT1 and miR-654-3p was detected by a dual luciferase reporter gene assay.
resultsThe expression of lncRNA NEAT1 was upregulated in the serum of the DFH group. After osteoblast differentiation treatment, lncRNA NEAT1 level reduced while the level of miR-654-3p increased. A targeting relationship was found between lncRNA NEAT1 and miR-654-3p.and the expression levels were significantly negatively correlated. The lncRNA NEAT1 affected cell activity and apoptosis levels of osteogenic differentiated cells by regulating miR-654-3p.
conclusionslncRNA NEAT1 expression was up-regulated in DFH patient serum, and it has high diagnostic value for delayed fracture healing. lncRNA NEAT1 targeting miR-654-3p affected the activity and apoptosis of osteogenic differentiated cells.
