We screened all patients attending our outpatient thyroid clinic for eligibility and recruited 19 patients for the study between January 2018 and July 2019. At screening all patients were hyperthyroid with a TSH level below 0.2 mlU/l and free T4 at or above 25 pmol/L or free T3 at or above 8 pmol/L. However, at the timepoint of the first study visit one female patient with Graves’ disease was already in a slightly hypothyroid state. Therefore we excluded this patient from the analysis.Thus, 18 patients (14 female/4 male) were included in the analysis. In the first 10 patients we performed only the interventional treatment visit with propranolol. In the last 8 patients, we conducted the treatment visit and also an additional control visit and the sequence of the visits was randomized (see Study flowchart, Flow chart of the study population showing included and excluded patients.They were on average 45 ± 17 years old and had a BMI 24 ± 4.5 kg/m². An average score of 14 points was achieved on the hyperthyroidism symptom scale (see Baseline characteristics.*p < 0.05, ***p < 0.001, ****p < 0.0001. N/A= not applicable.
