Following publication of the original article [1], an error was discovered in table 3 “Logistic regression model for use of antidepressants, sedatives and anti-epileptics, respectively, at one year following index date, for patients with LGG.” In this table, the numbers presented for anti-epileptics are equal to the numbers for the sedatives. There has been a copy error and numbers need to be adjusted. The new results do not change the conclusions. The updated table 3 is given below and the changed values are displayed in bold typeface.
