Text correction Adding/removing text In the published article, there was a mistake in the text. In the second sentence of the subsection Functional vocal symptoms (FVS) the statistical parameters for complex FVS were given as: "(mean: 43, range: 3–200, median: 21.5)". The correct sentence including the accurate statistical parameters is: "The mean number of "simple" FVS was much lower (mean: 2.2, range, 0-6, median: 2) compared to that of "complex" FVS (mean: 18.8, range: 3-72, median: 15)". A correction has been made to the section Results, MSMI-FTB, Functional vocal symptoms (FVS): "Functional vocal symptoms (FVS) All patients presented with "complex" and 28 (88%) with "simple" FVS. The mean number of "simple" FVS was much lower (mean: 2.2, range, 0-6, median: 2) compared to that of "complex" FVS (mean: 18.8, range: 3-72, median: 15). Altogether, we identified 471 different FVS. In four patients (12.5%) the number of FVS was <10, in 15 (46.9%) between 10-30, in five (15.3%) between 31-60, and in eight (25.0%) between 100-200. "Animal sounds" were identified in 11 patients (34.4%). Because of their high frequency and relative complexity, we classified them different from YGTSS as a separate category. The spectrum of "complex" FVS ranged from single words to 10-word sentences with neutral, socially inappropriate, and offensive content, mainly in German, but partly also in English language. The two by far most often used "complex" FVS were the German swear words "Arschloch" ("asshole") and "Fick dich" ("fuck you"). Since "complex" FVS showed a remarkable overlap, we clustered them depending on the topic as follows (in descending order): "fick/fuck", other swear words, radical right-wing statements, food-related words, and statements expressing disagreement (for details see Table 2). More than half of patients (n=17, 53.1%) reported a change in their voice pitch (low: n=9, 28.1%, high: n=3, 9.4%, fluctuating pitches: n=5, 15.6%) only occurring when pronouncing FVS."
