Table 3 Comparison between pooled analysis and unpooled analysis of matched case-control study on obesity. The column marked “Standard CLogit” displays results of a standard conditional logistic regression analysis for the matched case-control study design. The column marked “Pooled CLogit” displays results of pooled conditional logistic regression analysis with within-stratum pooling and poolsize g = 4. The OR and 95% confidence interval (CI) for the covariates are includes
