Exercise 2.22 on page 56 describes a study examining the link between miscarriage and the use of painkillers during pregnancy. Scientists interviewed 1009 women soon after they got positive results from pregnancy tests about their use of painkillers around the time of conception or in the early weeks of pregnancy. The researchers then recorded which of the pregnancies were successfully carried to term. The results are in Table D.16. (NSAIDs refer to a class of painkillers that includes aspirin and ibuprofen.) Does there appear to be an association between having a miscarriage and the use of painkillers? If so, describe the relationship. If there is an association, can we conclude that the use of painkillers increases the chance of having a miscarriage?

A recent study examined the link between miscarriage and the use of painkillers during pregnancy. Scientists interviewed 1009 women soon after they got positive results from pregnancy tests about their use of painkillers around the time of conception or in the early weeks of pregnancy. The researchers then recorded which of the pregnancies were successfully carried to term. The results are in Table 2.10.
