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

backgroundCD44 is a potentially interesting prognostic marker and therapeutic target in pancreatic cancer. The expression of CD44 has been reported to correlate with poor prognosis of pancreatic cancer in most literatures. The purpose of this study is to investigate the roles of CD44 in pancreatic caner, and their correlation with the prognosis of pancreatic cancer patients.

methods67 pancreatic cancer samples were collected in Xinhua hospital affiliated to Shanghai Jiaotong University dating from Jan 2010 to Dec 2012. Immunohistochemistry was applied to test the expression of CD44 in pancreatic cancer. The clinical data of the patients were collected including their gender, age, the histology and location, lymph node metastasis and so on. The correlation between the CD44 expression and the clinicopathological factors of patients with pancreatic cancer was analyzed by the software SPSS 13.0. We devise and synthesis of effectively interference of shRNA sequence of CD44, which was transefected to the pancreatic cancer cells PANC-1. Colony formation assay, cell migration assays and western blot were performed.

resultsThe positive rates of CD44 expression in pancreatic samples were 73.1% (49/67). Univariate analysis showed that there were a significant differences between the CD44 expression and the pancreatic cancer' T staging, TNM staging, lymph node metastasis, the differentiation degree, tumor location (P < 0.05). The Cox proportional hazards model showed that differentiation, CD44 expression and nerve invasion were independent prognostic factors. Knockdown of CD44 expression in pancreatic cancer cells led to decreased cellular proliferation and migration ability, accompanied by downregulation of p-ERK and p-AKT.

conclusionCD44 were related to the distant metastasis and aggressive malignant behaviors of pancreatic cancer. CD44 may regulate tumorigenesis and cancer metastasis partially via PI3K/AKT or MAPK/ERK regulatory pathway.
