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

Background: Salivary gland tumors are rare head and neck tumors with lymphoepithelial carcinoma (LEC) as a particularly infrequent variant. This study was an evaluation of the incidence of EBV infection in malignant salivary gland tumors with the emphasis on tumor type and geographical area. Methods: Five databases (PubMed, ScienceDirect, Scopus, Web of Science and Cochrane library) were searched for data on the prevalence of EBV in malignant salivary gland tumors. A random-effects meta-analysis was conducted with Comprehensive Meta-Analysis software version 2.0 (CMA 2.0) using the event rate (ER) for estimation of the incidence of EBV in the salivary gland tumor patients. Publication bias was lacking as assessed through funnel plot analysis with the Begg’s and Egger’s tests (P>0.05). Results: Out of 618 studies searched in databases, 19 reported the prevalence of EBV in malignant salivary gland tumors and were included in the present meta-analysis. The pooled ER of all studies was 44% [95%CI=21.5-69.2%] with extreme heterogeneity that for the studies in America was 44.2% [95%CI=4.1-93.6%], in Asia (249 patients) was 70% [95%CI= 33.4-91.6%] and in Europe was 11.8% [95%CI=7.4-85.5%] with extreme heterogeneity for three subgroups. The pooled ER for patients with undifferentiated carcinoma was 86.7% [95%CI=71.5-94.4%] compared with 6.6% [95%CI=2.5-16.5%] for other carcinomas. Conclusions: The incidence of EBV infection in malignant salivary gland tumors in Asia was greater than in Europe and America and the higher presence of EBV infection in LEC cases implies that EBV may be a major factor in its etiology or pathogenesis. Genetic, environmental and other geographic factors may also be involved.
