Impact of positive ZEB1 expression in patients with epithelial ovarian carcinoma as an oncologic outcome-predicting indicator.
Article in Oncology letters, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Several previous studies have revealed that the expression of zinc finger E-box binding homeobox 1 (ZEB1) in solid malignancies has an important significance on the clinical outcome of patients. However, the association between ZEB1 expression and survival in patients with epithelial ovarian carcinoma (EOC) remains unclear. The objective of the present study was to examine the extent of ZEB1 expression in EOC using immunohistochemical staining and investigate its association with patient outcome. A total of 40 patients with EOC initially treated with cytoreductive surgery and systematic chemotherapy were enrolled. ZEB1 expression was immunohistochemically categorized as negative, weak, moderate and strong according to the size of the staining area, and intensity. Subsequently, the associations between ZEB1 expression and recurrence/progression-free survival (RFS) rate were examined. The median age of patients in the current study was 54 years old (range, 22-72 years old). Among these patients, 15 (37.5%) exhibited International Federation of Gynecology and Obstetrics stage I disease, and 10 (25.0%), 13 (32.5%), and 2 (5%) had stage II, III, and IV disease, respectively. No patients with negative expression of ZEB1 experienced recurrence. In addition, ZEB1 expression was identified to be a significant predictor of a poorer RFS rate compared with negative expression (negative vs. weak, moderate and strong, P=0.0126). Furthermore, multivariate analyses revealed that moderate and strong ZEB1 expression levels were significant prognostic indicators of a poorer RFS rate in patients with EOC (hazard ratio, 2.265; 95% confidence interval, 1.072-8.021; P=0.0349). Confining analysis to patients with the clear-cell/mucinous histological type, those with moderate/strong ZEB1 expression demonstrated a significantly poorer RFS rate (P=0.0025). Positive ZEB1 expression may be an indicator to predict unfavorable RFS in patients with EOC.
