In the article titled “Managing Severe Asthma: A Role for the Long-Acting Muscarinic Antagonist Tiotropium” [1], there were errors in the description of Figure 1 and Table 1. The last sentence of Figure 1 should be updated from “LABA, long-acting β2-agonist” to “IL, interleukin; LABA, long-acting β2-agonist; LTRA, leukotriene receptor antagonist; OCS, oral corticosteroid; SABA, short-acting β2-agonist.” In addition, the last sentence of Table 1 should be updated from “LABA, long-acting β2-agonist; N/A, not applicable; NR, not reported; NS, not significant" to “ICS, inhaled corticosteroid; LABA, long-acting β2-agonist; N/A, not applicable; NR, not reported.”
