Fig. 2 — Correlation of BMI with quality of life and functional status. A higher BMI has a negative influence on quality of life as well as on functional disease specific status. (a) Scatter plot: significant positive correlation between BMI and MG-QoL15. Note: number of presentations: 53; number of patients: 27. Intercept: coefficient − 16.28; SE 12.01; p = 0.187. BMI: coefficient 1.29; SE 0.42; p = 0.005. (b) Scatter plot: significant positive correlation between BMI and MG-ADL. Note: number of presentations: 45; number of patients: 25. Intercept: coefficient 0.336; SE 0.527; p = 0.530. BMI: coefficient 0.05; SE 0.02; p = 0.017. The dependent variable MG-ADL was log(x + 1)-transformed

Abbreviations: BMI = body mass index, MG-ADL = Myasthenia Gravis-Activities of Daily Living scale, MG-QoL15 = 15-item Myasthenia Gravis-Quality of Life scale
