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

Integrin-linked kinase (ILK), an intracellular protein with serine/threonine protein kinase activities, plays a key role in integrin mediated cell-excellular matrix interactions, regulating cell proliferation, apoptosis, differentiation, and migration. ILK has been implicated in the development and progression in several malignancies. However, the role of ILK and ILK-mediated epithelial-mensenchymal transition (EMT) in the progression of oral squamous cell carcinoma (OSCC) has not been well understood. Here, by immunohistochemistry, we studied the expression of ILK, Snail, E-cadherin and N-cadherin in 98 primary OSCC specimens and analyzed their correlations with clinicopathologic profiles and clinical outcome. We also investigated the expression of ILK in 42 corresponding lymph node metastases. Positive expression of ILK protein was detected in 87.8 % of the primary tumors and 100 % of metastatic lesions. Increased ILK expression was correlated strongly with enhanced tumor invasion, higher tumor grade, advanced clinical stage, positive lymph node status and increased risk of recurrence. Higher ILK expression was also observed in lymph node metastases in comparison with the corresponding primary tumor. Moreover, up-regulation of Snail and N-cadherin and down-regulation of E-cadherin correlated significantly with both ILK over-expression and tumor invasion. Patients with higher ILK expression exhibited shorter disease-free survival while those with absent E-cadherin expression exhibited shorter overall and disease-free survival. Taken together, our results suggest that ILK may have an important role in progression and metastasis of OSCC, possibly through EMT involving up-regulation of Snail and consequent aberrant expression of E-cadherin and N-cadherin. ILK should be considered as a critical prognostic indicator for patients with OSCC.
