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

backgroundPorphyromonas gingivalis (P. gingivalis) is closely related to Oral squamous cell carcinoma (OSCC), and P. gingivalis outer membrane vesicles (OMVs) is the main pathogenic factor, which is associated with periodontitis, atherosclerosis and other diseases. However, few studies have reported an association between P. gingivalis OMVs and OSCC. The purpose of this study was to establish the clinical relationship between P. gingivalis and OSCC based on clinical samples. Further, the effect of P. gingivalis OMVs on OSCC was observed with cell model in vitro, and the possible molecular mechanism was discussed.

methodsImmunohistochemistry was used to detect the abundance of P. gingivalis in OSCC and its paired paracancer tissues, and to analyze the correlation between P. gingivalis and clinicopathological parameters of patients. P. gingivalis OMVs were isolated to observe its effects on the proliferation and migration of OSCC cell lines. RNA-seq was performed and the expression of differentially expressed genes (DEGs) was detected by real-time quantitative PCR (RT-qPCR) to explore the potential mechnism of P. gingivalis OMVs on OSCC progression.

resultsThe abundance of P. gingivalis in OSCC was higher than that in para-cancerous tissues, and was positively correlated with the degree of tissue differentiation (P = 0.028), T stage (P < 0.001), and clinical stage (P = 0.011). P. gingivalis OMVs promoted the proliferation and migration of HN6 cells, and promoted the proliferation of CAL27 cells, but had no significant effect on its migration. P. gingivalis OMVs treatment attenuated the expressions of TNFSF15, ZNF292, ATRX, ASPM and KIF20B in CAL27 and HN6 cells.

conclusionThis study suggests that P. gingivalis may be an indicator of poor prognosis for OSCC. P. gingivalis OMVs may down-regulate the expression of TNFSF15, ZNF292, ATRX, ASPM, KIF20B and participate in the occurrence and development of OSCC.
