Meta-Analysis on E-Cigarette Use and COPD Association, 15 Studies

Yanqiu Jiang's meta-analysis document, uploaded on 2026-04-22, synthesizes evidence from 15 observational studies to evaluate the association between e-cigarette use and chronic obstructive pulmonary disease. The analysis includes subgroup results for exclusive e-cigarette users, dual users, and former users. The document is a 7.0 MB DOCX file licensed under CC-BY-4.0.

Use Cases

• Conducting a systematic review on e-cigarette health effects based on the described literature search and inclusion criteria.
• Analyzing pooled odds ratios for COPD risk among different user groups (exclusive, dual, former) based on the reported meta-analysis results.
• Investigating potential publication bias in observational studies of e-cigarettes based on the described sensitivity analysis.
• Studying the independent association of e-cigarettes with COPD, separate from traditional smoking, based on the subgroup analysis of exclusive users.

Strengths

• The analysis is based on 15 included studies, providing a quantitative synthesis.
• Results include specific pooled odds ratios with 95% confidence intervals for multiple user subgroups.
• A sensitivity analysis was performed, and the description states no evidence of publication bias was observed.

Limitations

• The dataset is a single document; column-level data and row counts for the underlying studies are unavailable.
• The description metadata is limited; actual data quality and the full dataset of extracted study results require manual inspection after download.
• Freshness should be verified as the last update date is 2026-04-22.
