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

Tumor endothelial marker 7 (TEM7) is a new candidate of molecular target for antiangiogenic therapy. This study aims to evaluate its expression in gastric cancer (GC) and to explore the correlation between its expression and the clinical outcome of patients. Expression of TEM7 was analyzed in both tumor tissues and cell lines of GC by real-time quantitative RT-PCR (qRT-PCR) and Western blot. RNA interference (RNAi) approaches were used to investigate the biological functions of TEM7. The effects of TEM7 on cell migration and invasion were evaluated by Transwell assays. In vitro experiments revealed that TEM7 was significantly overexpressed in GC cell lines (N87, AGS and SGC-7901) by 2-fold to 4-fold, and knockdown of TEM7 could significantly inhibit cancer cell migration and invasion. For GC patients, TEM7 gene expression was elevated in tumors in most cases (25/31), and its expression was closely correlated with tumor differentiation, depth of cancer invasion, lymphatic metastasis and TNM stage. The overall survival of TEM7 (-) group was significantly higher than that of TEM7 (+) group (P = 0.048) and TEM7 (++) group (P = 0.003). TEM7 is highly expressed in GC and is likely correlated with tumor invasion and migration, and thus its expression is closely related to the clinical outcome of patients.
