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

The characteristics of cancer cells, such as invasiveness, are affected by the tumor microenvironment. Studies have shown that interleukin (IL)-6 and tumor necrosis factor (TNF)-α regulate the proliferation of lung cancer. However, few studies have focused on the effects of IL-6 and TNF-α on metastasis of lung cancer. The present study was designed to investigate whether IL-6 and TNF-α can promote metastasis of non-small cell lung cancer (NSCLC). Sixty-five tumor and matched adjacent tissue samples from patients with NSCLC and corresponding serum samples were collected. Thirty serum samples from healthy subjects were selected as controls. Real-time PCR and western blot analysis were used to measure IL-6, TNF-α, vimentin, E-cadherin, and N-cadherin expression in tissue samples; ELISA was used to measure IL-6 and TNF-α expression in serum samples. The correlation of serum levels of IL-6 and TNF-α with the clinical stage was analyzed; the correlation of IL-6 and TNF-α levels in serum with these tissues was analyzed; the correlation of serum levels of IL-6 and TNF-α with lymph node metastasis and distant metastasis was analyzed. Expression of IL-6 and TNF-α were significantly increased compared with controls in both serum and tissue; IL-6 and TNF-α levels were positively correlated with lymph node metastasis and distant metastasis; IL-6 and TNF-α levels were negatively correlated with E-cadherin level and were positively correlated with N-cadherin and vimentin levels. In conclusion, IL-6 and TNF-α can induce epithelial-mesenchymal transition, and subsequently promote metastasis of lung cancer. Anti-inflammation should be considered for the treatment of lung cancer.
