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

backgroundThe degree of intratumoral microvascular density is thought to affect tumor metastasis and prognosis in various human cancers, including gastric cancer. Despite recent medical advancements, gastric adenoma or adenocarcinoma remains a considerable therapeutic challenge. Endoscopic submucosal dissection (ESD) is a more recent approach that is now commonly used for radical resection of gastric adenoma and adenocarcinoma. AIM AND

methodsThe expression of vascular endothelial growth factor (VEGF), epidermal growth factor receptor (EGFR), and interleukin-6 (IL-6) are related to the prognosis of gastric adenocarcinoma. However, the expression of these factors in gastric adenoma/adenocarcinoma following ESD has not been clearly evaluated. Here, we report on our study of the expression of VEGF, EGFR, and IL-6 by immunohistochemical staining in extracted tissue from adenoma or adenocarcinoma of the stomach by ESD and subsequent evaluation of the correlation of VEGF, EGFR, and IL-6 with other clinicopathological parameters. The patient cohort consisted of 102 patients with adenoma or adenocarcinoma of the stomach.

resultsImmunohistochemical staining for VEGF and IL-6 was significantly higher in both high grade dysplasia and adenocarcinoma than in low grade dysplasia (P < 0.05). There was significant correlation between histological grade and intensity of immunohistochemical staining of VEGF (P = 0.039). Histological differentiation of adenocarcinoma was related to IL-6 expression (P = 0.028). The immunoreactivity of VEGF and IL-6 increased significantly in lesions >2 cm compared to lesions <2 cm (P < 0.05).

conclusionThe immunohistochemical expression of IL-6 and VEGF can be considered to be useful for clinical diagnosis and follow-up of adenoma or adenocarcinoma of the stomach.
