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

backgroundCullin4A (CUL4A), which is a component of E3 ubiquitin ligase, is implicated in many cellular events. Although the altered expression of CUL4A has been reported in several human cancers, the role of CUL4A in esophageal cancer remains unknown.

methodsWe investigated the CUL4A expression in primary esophageal squamous cell carcinoma (ESCC) tissue specimens from 120 patients by immunohistochemistry and explored its clinical relevance and prognostic value. Furthermore, the effect of the expression of CUL4A on cancer cell proliferation was analyzed in vitro using an siRNA silencing technique.

resultsThe higher expression of CUL4A was significantly associated with a deeper depth of tumor invasion (P < 0.001) and the presence of venous invasion (P = 0.014). The disease-specific survival (DSS) rate in patients with tumors that showed high CUL4A expression levels was significantly lower than that in patients whose tumors showed low CUL4A expression levels (P = 0.001). Importantly, the CUL4A status was identified as an independent prognostic factor for DSS (P = 0.045). Our results suggested that the CUL4A expression has significant prognostic value in ESCC. Furthermore, CUL4A gene silencing significantly inhibited the proliferation of ESCC cells in vitro. In addition, the knockdown of the CUL4A expression induced G1 phase arrest and increased the p21 and p27 protein levels.

conclusionsCUL4A might play an important role in regulating the proliferation of ESCC cells and promoting the development of postoperative recurrence.
