Page 308, column 2, paragraph 3, lines 1–8: the following sentence, which previously read:

Opicapone has the advantage of once-daily administration versus frequent administration with second generation COMT inhibitors, with entacapone administered with each levodopa dose (maximum of ≤ 10 doses/day) and tolcapone administered three times daily [1–3]. Tolcapone is also associated with an increased risk of hepatotoxicity (albeit very rare), which limits its use to patients who fail to respond to other COMT inhibitors [1–3].
