In this paper they were assessing the Neonatal outcomes in preterm multiples receiving layed cord clamping. They were measuring to see if there was any difference in various key delivery room measures and clinical outcomes. They used a hierarchy model with clustering around the pregnancy for mothers. They used both a mixed effect (ME) model and a generalized estimating equations (GEE). Continuous variables were analyzed using ME with exchangeable covariance structures and restricted maximum likelihoods. Categorical variables were analyzed using generalized estimating equations.
File size is too large to fit for some reason.
