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

backgroundStomatin-like protein 2 (SLP-2) is a member of the highly conserved stomatin protein family whose homologues span from Archaea to humans and include stomatin, SLP-1, and SLP-3. Several studies have indicated that overexpression of SLP-2 is strongly associated with adhesion and migration in several human cancers. The aim of the present study was to evaluate SLP-2 expression at the mRNA and protein level in patients with gastric cancer (GC) and to examine the relationships between SLP-2 expression, clinicopathological features, and prognosis.

methodsWe investigated SLP-2 expression in primary GC and paired normal gastric tissue by real-time PCR (RT-PCR; n = 16) and Western blot analysis (n = 32). Additionally, we performed immunohistochemistry (IHC) on 113 paraffin-embedded GC specimens, 30 matched normal specimens, and 30 paired metastatic lymph node samples.

resultsSLP-2 is overexpressed in GC compared with the adjacent normal gastric epithelium (p < 0.001), and high-level SLP-2 expression is significantly correlated with the depth of invasion, lymph node metastasis, distant metastasis, and American Joint Committee on Cancer (AJCC) stage. Furthermore, elevated SLP-2 expression is an independent prognostic factor in multivariate analysis using the Cox regression model (p = 0.005).

conclusionsOverexpression of SLP-2 may contribute to the progression and poor prognosis of GC.
