The Effect of Delayed Oncology Surgery on Survival Outcomes for Patients With Gastric Cancer During the COVID-19 Pandemic: Evidence-Based Strategies.
Synthesis in Frontiers in oncology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 1 of them a synthesis that pooled 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.
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
Objective: To evaluate the impact of delay in gastrectomy on gastric cancer patients' survival outcomes during the COVID-19 pandemic. Methods: Databases including PubMed, MEDLINE (using the Ovid platform), Embase, the Cochrane Library, COVID-19 Open Research Dataset Challenge, COVID-19 Research Database (WHO), ClinicalTrials.gov, and WHO International Clinical Trials Registry Platform were searched for studies of any design and in any setting that included patients with gastric cancer from their inception to July 31, 2021. Hazard ratio (HR) and 95% confidence intervals (CI) of research endpoints in each study were calculated. Statistical analyses were performed with Stata 12.0. Results: A total of 8 studies involving 4,052 gastric cancer patients were eligible and included in the present meta-analysis. The result of the meta-analysis was shown that delaying surgery for less than 8 weeks may not decrease OS (HR = 0.91, 95% CI: 0.80~1.04, p = 0.167) and DFS (HR = 0.96, 95% CI: 0.62~1.50, p = 0.872) in gastric cancer. Our meta-analysis also illustrated that delay in surgery for more than 4 weeks (HR = 0.85, 95% CI: 0.56~1.27, p = 0.421), 6 weeks (HR = 0.88, 95% CI: 0.61~1.27, p = 0.490), and 8 weeks (HR = 0.93, 95% CI: 0.80~1.07, p = 0.314) was also not associated with a decreased OS. Conclusion: A delay in surgery of less than 8 weeks is not associated with worse overall survival for patients with gastric cancer.
