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

C4.4A, a member of the Ly6/uPAR family of membrane proteins, has been identified as a metastasis-associated molecule, but little is known about its actual expression and possible function in head and neck squamous cell carcinoma (HNSCC). To explore diagnostic and prognostic roles of C4.4A in HNSCC, we investigated the expression of C4.4A in human HNSCC tissue array which contains 43 HNSCC, 6 epithelial dysplasia and 16 normal oral mucosa. Expression of C4.4A was significantly increased in epithelial dysplasia and HNSCC when compared with normal oral mucosa. Moreover, high C4.4A expression indicated a rather poor prognosis of HNSCC patients. To better understand the function of C4.4A in HNSCC progression, we investigated epithelial to mesenchymal transition (EMT) associated proteins including transforming growth factor (TGF-β1), Slug and CD147 in HNSCC. The expression of TGF-β1, Slug, and CD147 was significantly increased in HNSCC when compared with normal oral mucosa. Meanwhile, the expression of C4.4A was significantly correlated with TGF-β1, Slug, and CD147 in HNSCC tissue array. Furthermore, knockdown of C4.4A decreased the cell invasion and migration in CAL27 cell line and suppressed the EMT with increased E-cadherin and decreased N-cadherin and Slug. Our study demonstrated that C4.4A was a potential marker for prognosis of HNSCC, and C4.4A participated in EMT program in HNSCC progression.
