Meta-Analysis of Oral Hygiene and Gastric Cancer Risk, Updated to 2024

A systematic review and meta-analysis investigating the association between oral hygiene and gastric cancer risk. The study includes 12 studies sourced from PubMed, Embase, Web of Science, Scopus, and the Cochrane Library, with searches conducted up to April 2024. It was authored by Tangna Ge and published on figshare under a CC-BY-4.0 license.

Use Cases

• Assessing the pooled risk of gastric cancer based on tooth brushing frequency mentioned in the description
• Exploring geographic heterogeneity in the association between tooth loss and cancer risk as identified in the analysis
• Validating the robustness of meta-analysis findings through sensitivity analysis methods described
• Informing primary prevention strategies by integrating oral health metrics into cancer risk models

Strengths

• Includes 12 studies with pooled odds ratios calculated using a random-effects model
• Reports specific risk increases: 55% for infrequent brushing (OR 1.55) and 25% for tooth loss (OR 1.25)
• Conducts subgroup and sensitivity analyses to explore heterogeneity and robustness

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download
• Column-level documentation is absent; field semantics must be inferred after download
• The dataset is small (104.0 KB), indicating limited scope, likely containing the review manuscript rather than raw study data
