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 inflammation characterized by alveolar bone resorption caused by imbalance in bone homeostasis. It is known that autophagy is related to inflammation and bone metabolism. However, whether autophagy inhibitors could be used for periodontitis in animal models remains unknown. We investigated the role of two classical autophagy inhibitors, 3-methyladenine (3-MA) and chloroquine (CQ), on the development of rat experimental periodontitis in terms of the bone loss (micro-CT), the number of inflammatory cells (hematoxylin and eosin staining), and the osteoclastic activity (tartrate-resistant acid phosphatase staining). Expression of autophagy-related genes and nuclear factor kappa B p65 (NF-κB p65) were assessed by immunohistochemistry. Expression of Beclin-1 and microtubule-associated proteins 1A/1B light chain 3 (LC3) were analyzed by Western blot. To further observe the effect of autophagy inhibitors on osteoclasts (OCs) in vitro, bone marrow-derived mononuclear macrophages were used. Together, these findings indicated that topical administration of 3-MA or CQ reduced the infiltration of inflammatory cells and alveolar bone resorption in experimental periodontitis. Furthermore, 3-MA and CQ may attenuate activation of OCs by autophagy. Therefore, 3MA and CQ may have prophylactic and therapeutic potential for inflammation and alveolar bone resorption in periodontitis in the future.
