“Long-term clinical and real-world experience with pirfenidone in the treatment of idiopathic pulmonary fibrosis.” Vincent Cottin and Toby Maher. Eur Respir Rev 2015; 24: 58–64.

Unfortunately, there was a typographic error in this article. The sentence that read:

The mean daily dose of pirfenidone for all subjects during this time was 2332 mg·day⁻¹, with the maximum possible daily dose being 2403 mg·day⁻¹.

should have read as follows:

The mean daily dose of pirfenidone for all subjects during this time was 2070 mg·day⁻¹, with the maximum possible daily dose being 2403 mg·day⁻¹.

The online version of the article has been amended to reflect this correction.
