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

Microarray studies revealed down-regulation of PCDH9 mRNA level in lymph node metastasis of gastric cancer compared with the primary tumors. The expression of PCDH9 protein and its clinicopathological relevance were assessed on tissue microarrays of 1072 cases of gastric cancer. Its prognostic value was further evaluated on a small cohort of 175 gastric cancers. PCDH9 was down-regulated during the development and progression of gastric cancer. The overall rates of PCDH9 expression in normal, primary tumor, nodal and hepatic metastatic tissues were 100 % (1072/1072), 48.0 % (515/1072), 20.1 % (34/169), and 5.6 % (1/18), respectively. Positive staining of PCDH9 protein was significantly reversely correlated with tumor size, tumor differentiation, tumor invasion, lymph node metastasis, and disease progression. The Cox proportional hazards model revealed that the PCDH9 was an independent prognostic factor for gastric cancer. Therefore, decreased expression of PCDH9 is frequent in human gastric cancer metastasis and PCDH9 expression is an independent prognostic factor, suggesting that PCDH9 could be a promising biomarker of this malignancy.
