Statistical Significance of Eating Disorders and Adverse Perinatal Outcomes
Excerpt: The study by Linna et al1 posited that “eating disorders appear to be associated with several adverse perinatal outcomes, particularly in offspring.” The adverse outcomes included anemia, slow fetal growth, premature contractions, and perinatal death. However, this conclusion cannot be supported by the data because the authors failed to correct the standard value of P = .05 to account for the large number of hypothesis tests. This leads to what is known as type 2 error and causes a hypothesis to be accepted that is actually false.
