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

Aim: The reasons behind the high prevalence of poorly differentiated gastric cancer in young females remain unclear. Therefore, this study aimed to conduct a comprehensive genetic analysis to investigate the factors responsible for the high prevalence of poorly differentiated gastric cancer in young females. Methods: We analyzed 299 patients who underwent gastric cancer surgery at the Gunma University Hospital between April 2015 and December 2020. Among them, we selected cases of poorly differentiated gastric cancer in females, differentiated gastric cancer in females, and poorly differentiated gastric cancer in males, aged 30-50 years. Three eligible cases of each condition were found and included in the study. RNA was isolated from dissected formalin-fixed, paraffin-embedded tissue samples, followed by RNA sequencing. The results were analyzed using ingenuity pathway analysis to elucidate the mechanisms contributing to the high incidence of poorly differentiated gastric cancer in young females. Results: Dexamethasone, β-estradiol, and interleukin-1β were identified as significant upstream regulators associated with poorly differentiated gastric cancer in young females. The downstream target genes of β-estradiol included male germ cell-associated kinase, growth differentiation factor 6, endothelin 2, and collagen type XI alpha 1 chain. Conclusion: Our detailed RNA-seq analysis revealed that the female sex hormone, β-estradiol, plays a role in the development of poorly differentiated gastric cancer in young females.
