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

Vascular endothelial growth factor (VEGF) is considered as a prime mediator of angiogenesis and has been implicated in carcinogenesis and metastasis. Various studies examined the relationship between VEGF protein overexpression with the clinical outcome in patients with oral cancer, but yielded conflicting results. Electronic databases updated to March 2013 were searched to find relevant studies. A meta-analysis was conducted with eligible studies which quantitatively evaluated the relationship between VEGF overexpression and survival of patients with oral cancer. Survival data were aggregated and quantitatively analyzed. We performed a meta-analysis of 17 studies (n = 1,207 patients) that evaluated the correlation between VEGF overexpression detected by immunohistochemistry and survival in patients with oral cancer. Combined hazard ratios suggested that VEGF overexpression had an unfavorable impact on overall survival (hazard ratio [HR] = 1.89; 95 % confidence interval [CI], 1.24-2.55) and disease-free survival (HR = 2.08; 95 % CI, 1.14-3.02) in patients with oral cancer: 1.77 (1.09-1.44) in oral squamous cell carcinoma (SCC) patients and 4.28 (1.35-7.21) in adenoid cystic carcinoma (ACC) and mucoepidermoid carcinoma (MEC) of the salivary glands. No significant heterogeneity was observed among all studies. VEGF overexpression indicates a poor prognosis for patients with oral SCC, ACC, and MEC of the salivary glands.
