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

purposeTriple-negative breast cancer (TNBC), characterized by the absence of estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2, is a highly heterogeneous disease. Recent studies suggest that there are links between TNBC and the epithelial-mesenchymal transition (EMT). To identify prognostic biomarkers and novel therapeutic targets, vimentin, one of the most major factors associated with EMT was investigated in TNBC. MATERIALS AND

methodsSporadic invasive ductal carcinoma specimens were obtained from 659 Japanese patients, and 90 (14 %) cases were diagnosed as TNBC. The vimentin mRNA and protein expression levels were evaluated by quantitative reverse transcriptase-polymerase chain reaction and immunohistochemistry.

resultsThe mRNA expression of vimentin was significantly upregulated in the basal-type breast cancer cell line. Immunohistochemically, the vimentin expression was significantly higher (p = 0.0042) in TNBC compared with the other subtypes. Vimentin expression was associated with a younger age (p = 0.016), high nuclear grade (p = 0.023) and high Ki67 expression (p < 0.0001), and a poorer prognosis in terms of both the recurrence-free survival (RFS) (p = 0.0058) and overall survival (OS) (p = 0.013) in TNBC patients. A multivariate analysis showed that vimentin expression was an independent prognostic factor for the RFS (p = 0.043). Vimentin expression was also associated with a significantly shorter RFS (p = 0.021) and OS (p = 0.017) in patients with basal-like breast cancer (BLBC).

conclusionsThe elevated expression of vimentin contributes to the aggressive phenotype and poor prognosis in TNBC. Vimentin expression might be useful as a biomarker for the prognosis of TNBC.
