^aOverview of individual stuttering characteristics, including the percentage of stuttered syllables during baseline, number of stuttering events during the preoperative nrTMS-based language mapping, the individual prevalent stuttering event type, and the percentage of stuttering events classified as stimulation-induced language error for each nrTMS operator.

^bR= Repetition of syllables and/or phonemes, P=Prolongations, B= Block; named according to the frequency of symptom occurrence (from most to least frequent stuttering symptom).
