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
Gastric cancer remains a leading cause of cancer-related mortality worldwide. The prognosis often depends on early detection and understanding the molecular mechanisms involved in its progression. Periodic tryptophan protein 1 (PWP1) has emerged as a novel diagnostic marker, potentially linked to gastric cancer progression. This study aims to elucidate the impact of PWP1 on gastric cancer development, focusing on apoptosis, cell cycle regulation, and the role of p53. This study utilized gastric cancer cell lines to investigate the expression and functional role of Pwp1. Quantitative PCR and Western blot analyses were conducted to measure PWP1 expression levels. Apoptosis was assessed by using flow cytometry and TUNEL assays, and cell cycle analysis was performed to evaluate the impact of PWP1 modulation. Additionally, animal experiments were conducted using mouse models injected with gastric cancer cells, with PWP1 knockdown or overexpression, to observe tumor growth and progression. Statistical significance was evaluated using t-tests and ANOVA where appropriate. Elevated PWP1 expression was observed in gastric cancer tissues compared to normal tissues. PWP1's knockdown resulted in increased apoptosis and cell cycle arrest at the G1 phase, suggesting its role in promoting invasion and proliferation. Furthermore, animal experiments demonstrated reduced tumor growth in mice with PWP1 knockdown. PWP1 was found to transcriptionally regulate p53, affecting its expression and thereby influencing apoptosis and cell cycle pathways in gastric cancer. Our study identifies PWP1 as a novel oncogene frequently overexpressed in gastric cancer (GC). Through transcriptional regulation of p53, PWP1 enhances cell growth by influencing apoptosis and inducing G1 phase cell cycle arrest. These findings underscore PWP1 as a promising therapeutic target for treating GC, suggesting its potential for future clinical applications.
