In the Original Investigation titled “Association of Bone Mineral Density With the Risk of Intracranial Aneurysm,”1 published online October 16, 2017, there were errors in the data of the Results section of the text. The fourth sentence of the second paragraph of the Results section should read “The odds ratio (OR) ranged between 1.26 (95% CI, 1.00-1.58) and 1.30 (95% CI, 1.03-1.64) in all comparisons with statistically significant differences (Table 2).” The final sentence of the same paragraph should read “Apart from the lumbar spine BMD, the BMD of the other 2 skeletal sites showed similar associations, with the risk of IA and the strength of the associations increased slightly, with an OR ranging between 1.31 (95% CI, 1.02-1.69) and 1.35 (95% CI, 1.05-1.74) (Table 2).” This article was corrected online.
