Accutane’s side effects: An article in Saturday’s Section A about the possibility of the acne drug isotretinoin, best known by the brand name Accutane, being taken off the market because of side effects misstated the results of a study that compared people with inflammatory bowel disease to people without the disease. The article said the study showed 1.2% of people diagnosed with inflammatory bowel disease had used isotretinoin before diagnosis, compared with 1.1% who had not used isotretinoin. Instead, the study showed that 1.2% of people with inflammatory bowel disease had used isotretinoin before diagnosis, compared with 1.1% of people in the healthy group who had used the drug and not developed the disease.
