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

Treatment failure for lung adenocarcinoma is frequently due to lymph node metastasis and invasion to neighboring organs. The aim of the present study was to investigate the invasion- and metastasis-related gene, neural precursor cell expressed, developmentally downregulated 9 (NEDD9), in lung adenocarcinoma tissues and cell lines. The expression of NEDD9 was analyzed by the SP method of immunohistochemistry for 60 formalin-fixed and paraffin-embedded (FFPE) lung adenocarcinoma tissues in which 32 cases were metastastic and 28 were without metastases. NEDD9 mRNA expression and protein levels were quantified by fluorescence quantitative reverse transcription-polymerase chain reaction (FQ-PCR) and western blotting in the highly invasive lung adenocarcinoma cell lines A549 and 95D as well as in SPC-A-1 cells with low invasive potential. The immunostaining scores revealed a statistically significant difference between metastatic and non-metastatic lung adenocarcinomas (p<0.001). FQ-PCR and western blotting demonstrated that NEDD9 expression was higher in A549 and 95D compared to SPC-A-1 cells (P=0.003). Our results provide evidence that NEDD9 is upregulated in metastatic lung adenocarcinoma and in highly invasive lung adenocarcinoma cell lines, suggesting its potential involvement in regulating cell migration and invasion.
