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 c-ets-1 transcription factor has been involved in the in vitro transactivation of matrix-degrading protease genes that might play an important role in tumor invasion. Using in situ hybridization, we analyzed serial frozen sections for c-ets-1, collagenase 1, and urokinase-type plasminogen activator gene expression in 54 lung carcinomas including 34 non-neuroendocrine carcinomas (18 squamous carcinomas, 10 adenocarcinomas, 3 large cell carcinomas, and 3 basaloids) and 20 neuroendocrine carcinomas (7 small cell lung carcinomas, 4 large cell neuroendocrine carcinomas, 4 well differentiated neuroendocrine carcinomas, and 5 carcinoids). c-ets-1 gene was expressed in stromal cells in 44/54 lung carcinomas including one metastasizing carcinoid. c-ets-1 transcripts were also detected in cancer cells more frequently in neuroendocrine than in non-neuroendocrine carcinomas (P = 0.0059) and in stages III and IV and metastasis more frequently than in stages I and II ( P = 0.0065). Collagenase 1 gene was expressed in 16/34 non-neuroendocrine tumors and in 1/20 neuroendocrine tumors, either in stromal (12/17) or in cancer cells (6/17). Urokinase-type plasminogen activator mRNAs were expressed in 45/54 lung carcinomas in stromal and/or cancer cells. In non-neuroendocrine tumors, c-ets-1 and collagenase 1 gene expressions in stromal cells were correlated. These results demonstrate that the transcription factor c-ets-1, collagenase 1, and urokinase-type plasminogen activator are involved in lung cancer invasion and suggest that c-ets-1 protein might transactivate collagenase 1 gene during tumor invasion.
