1 · What the graph read from it

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.

2 · The registry

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

Periodontitis is an inflammatory disease that causes bone resorption. This study used a ligature-induced experimental periodontitis model to observe the kinetic process of microstructural changes in alveolar bone and introduced star volume analysis as a new methodology to assess microstructural changes. Thirty Wistar rats were used. To induce experimental periodontitis, ligatures were placed around the maxillary first molar. Rats were euthanized on days 0, 1, 3, 7, 14, and 28 after ligature placement. In addition to using hematoxylin and eosin staining, tartrate-resistant acid phosphatase (TRAP)/alkaline phosphatase (ALP) double staining, and micro-computed tomography were performed to analyze bone remodeling. From day 0 to day 7 (initiation phase), the model showed predominant inflammation with increased numbers of TRAP-positive cells, while ALP expression decreased. In contrast, from day 14 to day 28 (resolution phase), inflammatory cells and TRAP-positive cells decreased, whereas ALP expression recovered to levels comparable to that on day 0. Regarding microstructure parameters, in the initiation phase, bone volume fraction, bone mineral density, trabecular thickness, and star volume of the trabeculae decreased significantly, whereas trabecular separation and star volume of the marrow space increased significantly, indicating bone resorption. In the resolution phase, microstructure parameters normalized, indicated bone formation. We confirmed dynamic alveolar bone remodeling in ligature-induced periodontitis in rats. Furthermore, we assessed the potential for using star volume analysis as a sensitive new tool to clarify microstructural changes to alveolar bone in this model.
