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

backgroundCancer stem cells proved to have a vital role in cell migration, invasion, metastasis, and treatment resistance of colorectal cancer (CRC) that subsequently lead to poor clinical outcomes. These stem cells may be a novel therapeutic target for the management of CRC progression. Signals of the Notch-1 pathway are responsible for acquisition of stem cell characters. ALDH1 and CD44 are usually detected in stem cells in colorectal cancer.

aimThe aims of this work are to evaluate the immunohistochemical expression of cancer stem cell markers ALDH1, Notch1, and CD44 in colorectal cancer and investigate their correlation with clinicopathological characters and patient survival.

methodsParaffin-embedded specimens of 70 patients with primary colorectal carcinoma were analyzed for Notch 1, ALDH1, and CD44 expressions by immunohistochemistry.

resultsNotch1 was mainly located in the cytoplasm of CRC tissues, rarely expressed in adjacent normal tissues. A highly statistically significant relationship was found between grading, lymphovascular invasion, the degree of lymphocytic infiltration, peritumoral budding, lymph node ratio, lymph node metastasis, and Notch1 expression (p < 0.001). There was a highly statistically significant relationship found between AJCC stage and Notch1 expression (p < 0.001). CD44 was mainly located in the cell membrane of CRC tissues. A highly statistically significant relationship was found between grading (p = 0.006), lymphovascular invasion, the degree of lymphocytic infiltration, peritumoral budding, lymph node metastasis, lymph node ratio, and CD44 expression (p < 0.001). There was a highly statistically significant relationship found between AJCC stage and CD44 expression (p < 0.001). ALDH1 was detected in the cytoplasm of the CRC tissue. A highly statistically significant relationship was found between grading, lymphovascular invasion, the degree of lymphocytic infiltration, peritumoral budding, lymph node metastasis, lymph node ratio, and ALDH1 expression (p < 0.001). There was a highly statistically significant relationship found between AJCC stage and ALDH1 expression (p < 0.001). There is a highly statistically significant direct correlation between Notch1, CD44 expression, and ALDH1 expression (p < 0.001).

conclusionsThere is a substantial correlation between Notch 1, ALDH1, and CD44 as cancer stem cell markers and lymph node metastasis, advanced stage and tumor recurrence in colorectal carcinoma.

conclusionExpression of stem cell markers ALDH1, Notch1, and CD44 correlates with poor prognosis in a CRC and represents an independent prognostic factor. They are associated with a feature of epithelial-mesenchymal transition evidenced by their association with high tumor burden.
