Impact of the change in ISTH-BAT cutoff value at the age of 18 years. (A) Total ISTH-BAT is not significantly different from the age of 12 to 27 years. The P values are the outcomes of independent t tests. (B) Proportion of patients with abnormal ISTH-BAT scores in individuals aged 12 to 27 years. Before the age of 18 years, abnormal ISTH-BAT is defined as a score ≥3, whereas from ≥18 years, abnormal scores are defined as ≥6 in women and ≥4 in men. The P values are the outcomes of independent t tests. (C) Proportion of abnormal ISTH-BAT scores at ages 12 to 27 years stratified by sex.
