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
Background: The introduction of epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) has revolutionized advanced non-small cell lung cancer (NSCLC) treatment. However, their efficacy can be compromised by concurrent use of gastric acid suppressants (GASs), such as proton pump inhibitors (PPIs) and histamine 2 receptor antagonists (H2RAs). This study aimed to update the evidence on the impact of GASs on the overall survival (OS) and progression-free survival (PFS) in patients on EGFR-TKI treatment. Methods: A systematic review and meta-analysis were conducted using data from PubMed, Embase, Cochrane Library, Web of Science, Scopus, KoreaMed, and preprint repositories. Data from 13 retrospective studies, involving 10,814 patients, were analyzed. Results: Overall, 34.6% of the patients used GASs, with most being Asian females and non-smokers. Most patients had EGFR-mutated adenocarcinoma, reflecting typical EGFR-TKI usage scenarios. Concurrent use of GASs was significantly associated with reduced OS [hazard ratio (HR) =1.34, 95% confidence interval (CI): 1.26-1.42], and PFS (HR =1.52, 95% CI: 1.25-1.86). In subgroup analysis, PPIs had a more negative impact on OS (HR =1.64, 95% CI: 1.51-1.79) than did H2RAs (HR =1.11, 95% CI: 0.95-1.31). Longer overlap times of GASs correlated with a higher trend in HRs for OS. However, the results for PFS were not significant in both subgroup analyses. Conclusions: Concurrent use of GASs with EGFR-TKIs is linked to poorer OS and PFS in patients with advanced NSCLC. Careful consideration is advised when prescribing GASs, including adjusting administration timing, minimizing overlap duration, or opting for H2RAs over PPIs. Further research is needed to optimize treatment protocols, specifically addressing the duration of overlap time, to improve patient outcomes.
