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

backgroundMicrosatellites stability (MSS) colon cancer patients exhibit a significant suppressive immune status, and the functional status of tumor NLRP3 immunosomes plays an important role in regulating the tumor immune microenvironment, but whether they are involved in the regulation of immunosuppression in MSS patients is unclear. Therefore, further exploration of the relevant molecular mechanisms is urgently needed.

methodsThe Cancer Genome Atlas-Colorectal Cancer (TCGA-COAD) Masked Somatic Mutation data, clinicopathological data were obtained, analyzed, and visualized using the 'maftools' in R package. Tissue microarray (TMA) used for this study includes 100 unselected, non-consecutive, primary, and sporadic CRCs treated between April 2006 and October 2010 in Tianjin Medical University General Hospital and 60 adjacent noncancerous tissues. Demographic and clinicopathological variables were collected, and the clinical value and prognostic impact of NLRP3 expression were analyzed. Tissue immunofluorescence (IF) was applied to investigate the colocalization expression of NLRP3 and ASC in tumor cells. The Vectra 3.0 Automated Quantitative Pathology Imaging System was used to obtain spectral information the NLRP3-ASC colocalization was analyzed by the Fiji Plugin "Coloc2". Cytotoxic T lymphocytes and M2 macrophages in tumor tissue were evaluated by immunohistochemistry. RESULTS AND

conclusionIn patients with MSS-CRC, aberrant activation of NLRP3 immunosome was significantly associated with lymph node metastasis of tumors. It is also closely related to the polarization of M2 macrophages in the tumor microenvironment, and further affects the infiltration of CD8+T lymphocytes, thereby creating a suppressive immune microenvironment.
