Change in non-HDL cholesterol (mg/dL) associated with each 1 lb. change in birth weight, among US 4–12 year-olds, using unweighted (UNWT), fully-weighted (FWT), trimmed weight (TWT3), pooled weight (PWT), and fractional Bayes factor pooled weight (PWFT2) estimators; unadjusted and adjusted for age, gender and age × gender interactions. Point estimates for PWT and PWTF2 models from posterior median; 95% CI or PPI in subscript. RMSE=estimated root mean square error, treating fully-weighted estimator as unbiased in expectation. Data from National Health and Nutrition Examination Survey III.
