I sent an email to editorial.office@frontiersin.org. If they reply, I will post their response here. Subject: elementary math error in journal article https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3615184/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3615184/ was linked to and discussed today from Hacker News (a popular discussion board for software engineers) here https://news.ycombinator.com/item?id=22307445 https://news.ycombinator.com/item?id=22307445. In the ensuing discussion a poster noticed that the journal article contains an elementary math error: "if schizophrenia occurs at a rate of 0.72% in the population (McGrath et al., 2008) and congenital blindness occurs at an estimated rate of 0.03% in people born in the 1970s and 1980s (based on Robinson et al., 1987), then the joint probability of a person having both conditions, if the two are independent, would be 0.02% or 2 out of every 10,000." 0.72% * 0.03% is actually .0002% or 2 out of every 1,000,000. Despite the article being several years old, I thought you might want to know. -harryh
