A Method of Data Extraction Based on Excel for Incomplete Data in Diagnostic Meta-Analysis

Diagnostic meta-analysis has become an important method of evidence-based medicine study. However,most of the original study did not offer the comprehensive data, which led to the study cannot be incorporated in meta-analysis and reduce the effectiveness of diagnostic. We describe several situations of insufficient data and the principle of the data extraction in diagnostic analysis. Excel was exploited to calculate the extracted data by application data analysis when complete data are unavailable in diagnostic meta-analysis.
