Score distribution patterns of studies and mouse genes with increased or decreased thrombosis tendency or bleeding. Indicated are score distributions per class of numbers of mouse genes (A) or numbers of studies (B). Classes I-III refer to arterial thrombosis in vivo, systemic thromboembolism, and thrombus formation in vitro, respectively; class IV refers to tail-bleeding times. In all cases, scoring was at 5-point scale. Studies using mice with noncomparable genetics (eg, gain-of-function mutations) were not included. (C) Numbers of mouse genes with altered scores in classes I-III (5-point scale), in combination with prolonged (−2/−1), unchanged (0), or shortened (+1/+2) tail-bleeding time (class IV).
