FIGURE 5.22 Plasma-aldosterone concentrations in 53 Caucasian and 46 African American children. Values within the shaded area were undetectable (< 50 pmol/L). The solid horizontal lines indicate the mean values, and the broken horizontal lines indicate the mean ±se. The concept of standard error (se) is discussed in Chapter 6.
Pregnant women with gestational diabetes mellitus (GDM) are at risk for long-term weight gain and subsequent development of type II diabetes. A pilot weight loss clinical trial was conducted where women with GDM were randomized to either an active intervention using a web-based delivery or a control intervention (Nicklas et al. [3]). Women were randomized at 6 weeks postpartum and then were seen at follow-up visits at 6 months and 12 months postpartum. At 12 months postpartum, women in the active group lost a mean of 0.2 lb. with a standard deviation of 15.4 lbs.
What is the probability that a control group woman was at or below her pre-pregnancy weight at 12 months?
Hint: Make the same assumptions as in Problem 5.53.
