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

CD44 variant 6 (CD44 v6) is well known as a useful marker of tumor progression; however, its relationship to prognosis has not yet been elucidated. In this study, we investigated the expression of CD44 v6 in colorectal cancer to analyze its relationship to hepatic metastasis as well as to prognosis. Tumor tissues were obtained from 42 patients with colorectal cancer who underwent curative resection with follow-up periods ranging from 5.9 to 71.3 months. There were 21 patients (50%) whose tumors were positive for CD44 v6, with no significant difference between colon and rectal cancer. CD44 v6 staining was significantly related to Dukes' classification as well as to hepatic metastasis. The 5-year survival rate was significantly higher in patients with CD44 v6 negative cancer (84%) than in those with CD44 v6 positive cancer (31%). Thus, we concluded that CD44 v6 could be a reliable prognostic indicator, as well as a predictor of metastatic potential after curative surgery for colorectal cancer.
