ZAK Gene Expression in Patients with Helicobacter pylori Infection.
Article in Journal of gastrointestinal cancer, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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.
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
backgroundZAK protein is a member of the MLK family proteins defined as mediators in the cell cycle. A survey of ZAK gene expression in gastric antral epithelial cells (GAECs) of gastritis and gastric adenocarcinoma patients with Helicobacter pylori genotypes infection can elucidate carcinogenesis of H. pylori genotypes.
methodsIn a case-control study, ZAK gene expression was evaluated in GAECs biopsy samples of gastritis and gastric adenocarcinoma patients with (n 23, 21) and without H. pylori infection (n 27, 32), respectively. Total RNA was extracted from each gastric antral biopsy samples and cDNA synthesized by using Takara kits. H. pylori virulence genes֝ cDNA were detected by traditional PCR and specific primers. The ZAK gene expression was measured using the relative Real-Time RT PCR.
resultsThe prevalence of gastric adenocarcinoma was the highest in man and 61-85 aged groups (p < .05). There was no significant correlation between the prevalence of H. pylori infection and patients' demographic groups. This study showed that ZAK gene overexpression gradually increases with increasing age and tumor grade among gastric adenocarcinoma patients. The gastric antral biopsy samples with H. pylori vacA s1m2 genotype infection showed a weak correlation with ZAK gene overexpression (p < .1).
conclusionZAK gene expression was higher in GAECs of gastritis cancer than in gastric adenocarcinoma, indicating the protective effect of ZAK against gastric cancer (p < .005). Reducing ZAK gene expression shows the negative correlations with H. pylori infection and gastric adenocarcinoma.
