Erratum

In the January 2019 article "Migraine: Expanding our Tx arsenal" (J Fam Pract. 2019;68:10-14,16-24), Table 2: Establishing the differential diagnosis of headache provided information that was incorrectly categorized. The table should not have included "Temporal arteritis" as a trigger for a headache caused by infection. Rather, the table should have listed "Temporal arteritis" among the triggers for a headache caused by an autoimmune disorder. In addition, "Acute and chronic sinusitis" and "Meningitis" should not have been listed as triggers for a headache with an iatrogenic or intoxication cause. Rather, they should have been the only triggers attributed to headaches with an infectious origin.
