A 2 Problem 1: Modeling the complexity of sickle cell disease pathophysiology is difficult. Creating a disease severity score that models the risk of death would be clinically useful. Using data from 3380 patients followed in the Cooperative Study of Sickle Cell Disease (CSSCD), Sebastiani, et al. created a severity score ranging from 0 (least severe) to 1 (most severe). Recruitment for CSSCD started in 1978 and continued for some patients into 1988. All participants were followed on average for 5 years. Several variables were recorded, including: participant age in years, race category, severity score, and total bilirubin level in mg/dL at enrollment, and adverse events (e.g., pain) and outcomes (death or survival) over study follow- up. Age was later grouped into three age categories (2-18 years, 19-40 years and greater than 40 years). [Source: Sebastiani, et al. Blood 2007; 110: 2727-2735] Use this information to answer questions A thru G. A.
