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

backgroundTissue factor (TF) is emphasized as the promising target in the future targeted therapy strategy for colorectal cancer (CRC). Recent evidence showed that TF expression is under the control of K-ras and p53. However, a comprehensive evaluation of TF expression, K-ras status, and p53 mutation has not been systematically analyzed. The aims of this study were to identify the percentages of positive TF in CRC patients; analyze the associations of TF expression, K-ras status, and p53 mutation; and evaluate the prognostic value of TF in CRC patients.

methodsNinety-six CRC samples were tested for TF expression, p53 mutation, and K-ras status by semiquantitative immunohistochemistry, Western blotting analysis, direct sequencing, and real-time quantitative PCR. Associations were sought with TF expression and clinical outcomes.

resultsTF expression was related to clinical stages, tumor differentiation, and tumor size. The positive proportions of TF expression on tumor cells and tumor vascular endothelial cells were 70% and 53% respectively in CRC patients. The positive proportion of TF co-expression on both cancer cells and tumor vascular endothelial cells was 40%, compared to an 83% total TF positive proportion in CRC patients. TF expression on CRC appeared to be increased with K-ras and/or p53 mutation(s). Disease-free survival and overall survival were significantly reduced in CRC patients with high TF expression.

conclusionsTF may participate in both K-ras and p53 mutations involved in colorectal carcinogenesis and could be considered as a prognostic indicator for patients CRC.
