Distribution of age and age at onset in MwoA and MwA patients. Parameters of age and age at onset for different groups are presented as boxplots, which indicate the median and quartiles with whiskers reaching up to 1.5 times the interquartile range. The violin plot shows the kernel probability density, i.e., the width of the shaded area represents the proportion of the data located therein. The average age of MwA group was younger than MwoA group (34.14 ± 13.67 years vs. 39.33 ± 11.96 years, p < 0.0001), and the age at onset was also younger in MwA group (26.57 ± 13.57 years vs. 28.72 ± 11.94 years, p < 0.0001). *: p < 0.05, **: p < 0.01, ***: p < 0.001
