P-values are from analysis variance model comparing mean values of putative risk factor between cases and controls, with adjustment for study site.
Non-imputed effect estimates are for complete case analysis using numbers of subjects in columns headed n.
Site-adjusted effects were computed in logistic regression models where the putative risk factor as the main explanatory variable and study site as covariate.
Fully-adjusted effects were computed in logistic regression models that additionally include covariates of age group, gender and race/ethnicity.
SOR is standardized odds ratio from a logistic regression model evaluating the linear effect of the risk factor that was standardized by z-score transformation
