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

Porphyromonas gingivalis (P.g.), which is a potential pathogen for periodontal diseases, contains lipopolysaccharide (LPS), and this endotoxin stimulates a variety of cellular responses. At present, P.g.-derived LPS-induced cellular responses in human periodontal ligament fibroblasts (PDLFs) are not well characterized. Here, we demonstrate that P.g-derived LPS regulates inflammatory responses, apoptosis and differentiation in PDLFs. Interleukin-6 (IL-6) and -8 (IL-8) were effectively upregulated by treatment of P.g.-derived LPS, and we confirmed apoptosis markers including elevated cytochrome c levels, active caspase-3 and morphological change in the presence of P.g.-derived LPS. Moreover, when PDLFs were cultured with differentiation media, P.g.-derived LPS reduced the expression of differentiation marker genes, as well as reducing alkaline phosphatase (ALP) activity and mineralization. P.g.-derived LPS-mediated these cellular responses were effectively abolished by treatment of mitogen-activated protein kinase (MAPK) inhibitors. Taken together, our results suggest that P.g.-derived LPS regulates several cellular responses via activation of MAPK signaling pathways in PDLFs.
