Effects of Porphyromonas gingivalis extracellular vesicles on human periodontal ligament fibroblasts.
Article in International journal of clinical and experimental medicine, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
The purpose of this study was to investigate the influencing mechanism of Porphyromonas gingivalis extracellular vesicles on human periodontal ligament fibroblasts to better understand the pathogenesis of periodontitis, the major cause of adult tooth loss. Human periodontal ligament fibroblasts were cultured and randomly assigned to a control group and an extracellular vesicles (ECV) group. The ECV group was exposed to isolated Porphyromonas gingivalis extracellular vesicles; the control group was not exposed. Western blotting was used to detect expression of matrix metalloproteinase 1 (MMP-1) and tissue inhibitor of metalloproteinase-1 (TIMP-1), and RT-PCR was used to detect mRNA expression of alkaline phosphatase (ALP). When human periodontal ligament fibroblasts were processed by Porphyromonas gingivalis extracellular vesicles (ECV), protein expression levels of both MMP-1 and TIMP-1 were significantly higher than that of the control group (P<0.05). In contrast, ALP mRNA expression in human periodontal ligament fibroblasts processed by ECV was significantly lower than that of the control group (P<0.05). Porphyromonas gingivalis extracellular vesicles can up-regulate expression of MMP-1 and TIMP-1 protein and ALP mRNA of human periodontal fibroblasts.
