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

objectiveThe process of epithelial-mesenchymal transition (EMT) clearly contributes to cancer metastasis. The aim of this study was to investigate the expression of the EMT-related transcription repressor ZEB1 and the expression of EMT-associated markers (E-cadherin, β-catenin and N-cadherin) in cervical squamous cell carcinoma. In addition, the role of ZEB1 and these EMT-associated markers in the progression and metastasis of cervical squamous cell carcinoma was explored.

methodsThe expression of ZEB1, E-cadherin, β-catenin and N-cadherin was evaluated in 81 specimens of cervical squamous cell carcinoma by immunohistochemistry; the clinicopathological significance of these markers was then analyzed.

results1) Of the 81 samples, 37 cases (45.7%) were positive for ZEB1, and nuclear expression of ZEB1 in tumor cells was positively associated with the differentiation status of the tumor tissue (P < 0.05), vascular invasion (P < 0.05) and lymph node metastasis (P < 0.05). 2) The loss of E-cadherin and β-catenin expression in tumor cells and the acquisition of N-cadherin expression were positively associated with the differentiation status of the tumor tissue (P < 0.05) and with the occurrence of vascular invasion (P < 0.05). 3) A significant negative correlation was observed between ZEB1 and E-cadherin expression (Spearman = -0.636, P < 0.05) and between ZEB1 and β-catenin expression (Spearman = -0.417, P < 0.05). Moreover, a significant positive correlation was observed between ZEB1 and N-cadherin expression (Spearman = 0.557, P < 0.05).

conclusionsThese results emphasize the role of EMT in cervical squamous cell carcinoma. The upregulation of ZEB1 is associated with the abnormal expression of E-cadherin, β-catenin and N-cadherin, which might promote the progression and metastasis of cervical squamous cell carcinoma.
