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.
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
backgroundContactin1 (CNTN1), a member of the immunoglobulin superfamily, is known to correlate with tumor development and progression. Although recent studies have found that elevated CNTN1 has been demonstrated in some types of cancers, the expression and prognosis of CNTN1 in colorectal cancer (CRC) are unclear. Here, we aimed to determine the clinicopathological characteristics and prognostic role of CNTN1 in CRC patients.
methodsThe protein expression of CNTN1 in tumor tissues was evaluated by immunohistochemistry. In addition, the mRNA and protein expressions of CNTN1 were examined by qRT-PCR and Western blotting analysis in 40 matched adjacent normal mucosa samples. The relationships of CNTN1 with clinicopathological data and prognosis significance were analyzed.
resultsImmunohistochemical consequence suggested that the protein level of CNTN1 was obviously raised in CRC compared with adjacent normal mucosa tissues (56.9% vs 10.3%, P< 0.05). In addition, we detected a significant increase in CNTN1 mRNA and protein levels in CRC tissues compared with the matched adjacent normal mucosa tissues. Moreover, increased CNTN1 exprssion was significantly associated with tumor size, lymph node metastasis (LNM), tumor node-metastasis (TNM) stage and carcino-embryonic antigen (CEA) in clinical analysis. Kaplan-Meier analysis suggested that patients with CNTN1 over-expression showed worse overall survival (OS) (P= 0.001). Multivariate analysis indicated that high CNTN1 expression was an independent predictor for poor OS in CRC patients (P= 0.028). Further analysis revealed that patients with high CNTN1 combined with LNM present accurately predicted poorer outcome.
conclusionTaken together, the findingsindicate that CNTN1 plays a significant role and serve as a potential biomarker for the prediction of adverse prognosis in CRC. Intriguingly, high express of CNTN1 + LNM-present combination may improve the accuracy of prognosis.
