Values are reported as absolute numbers (percentages). ↑ indicates value above ULN, and ↓ indicates value below LLN.
aPTT,activated partial thromboplastin time; HMB, heavy menstrual bleeding ; LLN, lower limit of normal; MCV, mean corpuscular volume; N, number; PT, prothrombin time; ULN, upper limit of normal.
