In the original article, there was a mistake in Table 1 as published. For ‘Days from symptom onset to treatment,’ the IFN+ARB and ARB values were inadvertently switched. IFN+ARB should be 8.0 [5.0,11.0] and ARB should be 17.0 [10.0, 22.0]. The corrected Table 1 appears below. The authors apologize for this error and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
