In the article “A Nationwide Cohort Study of Oral and Depot Antipsychotics After First Hospitalization for Schizophrenia,” by Jari Tiihonen et al. (Am J Psychiatry 2011; 168:603–609), in the first sentence of the second paragraph of the Results section, the mean follow-up period of 2 years (5,221 person-years) reflects the potential time frame for discontinuation of medication. However, the actual mean follow-up time in the analysis of all-cause discontinuation was 0.5 years, and the number of person-years was 809, since follow-up for any given patient stopped after discontinuation of medication. The actual numbers of person-years for each antipsychotic are listed in Figure S1 in the online data supplement.
