Pre-eclampsia is a condition in pregnancy characterized by high blood pressure, and sometimes also including swelling and urinary protein. If left untreated, it can lead to serious and potentially fatal pregnancy complications. Gestational diabetes is a risk factor for pre-eclampsia; those diagnosed with GD in the second trimester are at increased risk of developing pre-eclampsia later in the pregnancy. Using medical records from a SRS of pregnancies, researchers made the following 2 x 2 table: Pre-eclampsia No pre-eclampsia GD 6 40 No GD 28 613 a) What was the overall risk of pre-eclampsia in the sample? b) What was the risk of pre-eclampsia in those who also developed gestational diabetes? c) In this case, the risk is just a probability of an event occurring, which is estimated from the sample proportion. Instead of counts, we could have been given proportions/probabilities instead. Use the 2x2 table to fill in the blanks in the following: From a SRS of n=______ pregnancies, we found: P(GD but not pre-eclampsia)= ______ P(Pre-eclampsia but not GD) = ______ P(Both Pre-eclampsia and GD) = ______ d) Using the numbers you computed in c, what is the probability someone with GD also developed pre-eclampsia? (Note: This answer should match part b.- it's asking for the same thing)
