Errors in Figures 1 and 2

In the Original Investigation titled “Real-world Effectiveness of Pharmacologic Treatments for the Prevention of Rehospitalization in a Finnish Nationwide Cohort of Patients With Bipolar Disorder,”¹ published in the April 2018 issue, there were errors in the P values regarding 2 types of medication in Figure 1 and 4 types of medication in Figure 2. In Figure 1, the false discovery rate (FDR)–corrected P value should include the superscript “a” for antidepressants and for mood stabilizers (all) to indicate significance after Benjamini-Hochberg correction for 5% FDR. In Figure 2, the P values should be .02 for antidepressants, .65 for antipsychotics, and less than .001 for mood stabilizers (all); the FDR-corrected P value should be .06 for antidepressants, .74 for antipsychotics, and .001 for mood stabilizers (all); and the FDR-corrected P value should include the superscript “a” for mood stabilizers (all) and for quetiapine to indicate significance after Benjamini-Hochberg correction for 5% FDR.
