Over-expression of HDAC8 down-regulate CDKN2A is associated with worse prognosis of esophageal squamous cell carcinoma.
Article in Translational cancer research, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It has been retracted, and should not be counted. Not yet cited in PubMed.
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
backgroundThe epigenetic alteration has an impact on cancer cell cycle regulation. Expression of histone deacetylase 8 (HDAC8) ruled out the expression of cyclin-dependent kinase inhibitor 2A (CDKN2A) and this is linked with the prognosis of Esophageal cancer (EC) patients.
methodsBy the immunohistochemical staining, we examined the expression status of HDAC8 and CDKN2A protein of 110 esophageal squamous cell carcinoma (ESCC) patients in the tissue microarray. The nuclear staining intensity was counted by immunoreactivity scoring ranging from 0 to 12 and grouped them into two; weak or non-expression and over-expression.
resultsThe median follow-up duration of our study was 71 months postoperatively. Up-regulation of HDAC8 expression and down-regulation of CDKN2A (p16) indicate decreased 5-year overall survival (OS) (P=0.003) and (P=0.001) respectively and progression-free survival (PFS) (P=0.005, P=0.001) respectively, which are statistically significant and determined by Kaplan-Meier estimates using log-rank test. Consequently, HDAC8 and CDKN2A act as an independent prognostic biomarker, for OS and PFS that analyzed by multivariate cox-regression analysis, HR 1.173 with 95% CI: 0.215-6.416 and P=0.003 and HR 1.217 with 95% CI: 0.224-6.600 and P=0.005 respectively. Spearman rank test establish the negative correlation between HDAC8 and CDKN2A.
conclusionsOver-expression of HDAC8 and weak or no expression of CDKN2A have a worse impact on EC patients and indicate poor survival and progression of the disease and act as a promising prognostic parameter.
