41 studies comprising data from 47,743 humans were analyzed in this meta-analysis. The overall seroprevalence of H9N2 infection among humans in China was 4.10% (95%CI= 3.20-5.07). The review was conducted by Yanping Qi of Anhui University of Science and Technology, covering literature from inception to March 20, 2020.
Use Cases
- Modeling H9N2 infection risk based on demographic characteristics mentioned in the description
- Analyzing regional differences in seroprevalence based on north China vs. other regions data
- Evaluating the impact of test method and sampling time on seroprevalence estimates
Strengths
- Analysis includes data from 47,743 humans across 41 studies
- Provides specific seroprevalence estimates with 95% confidence intervals (e.g., 4.10% overall, 5.94% in north China)
- Identifies associations with test method, sampling time, gender, and demographic characteristics
Limitations
- Row count for the underlying dataset is unknown, which may limit suitability assessment
