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

BACKGROUND AND

objectiveThe aim of this study is to investigate the expression of Claudin-7, Slug and their correltion with clinicopathological characteristics in lung squamous cell carcinoma and adenocarcinoma. We also investigated the relationship between the two factors.

methodsThe expressions of Claudin-7 and Slug in proteins were detected in 101 cases of lung squamous cell carcinoma and adenocarcinoma samples by immunohistochemistry SP method, and Western blot was applied to detect the expressions of Claudin-7 and Slug in 30 specimens of fresh lung cancer and corresponding paracancerous tissues.

resultsThe expression of Claudin-7 was remarkably decreased in squamous cell carcinoma and adenocarcinoma tissues compared with normal lung tissue, and its expression level was closely correlated with differentiation grade and lymphatic metastasis (P<0.05), whereas the expression of Slug was significantly higher in cancer tissues than that in normal lung tissue. Outside differentiation grade and lymphatic metastasis, the expression of Slug was related to TNM stage (P<0.05). The expression of Claudin-7 was negatively correlated with the expression of Slug in lung squamous cell carcinoma and adenocarcinoma (r=-0.566,8).

conclusionThe down-regulation of Claudin-7 and overexpression of Slug might be one of pertinent biological markers for malignant transformation and metastasis of lung squamous cell carcinoma and adenocarcinoma.
