CLT for different combinations of levels of fibrinolytic factors. Numbers in the squares indicate the number of control subjects included in each category. Cutoffs for fibrinolytic factors (μ = population mean; SD = standard deviation): low: less than μ minus two-thirds SD; intermediate: μ minus two-thirds SD to μ plus two-thirds SD; high: more than μ plus two-thirds SD. Cutoff for CLT low: less than μ minus one-third SD; intermediate: μ minus one-third SD to μ plus one-third SD; high: μ plus one-third SD to μ plus 2SD; very high: more than μ plus 2SD. Cutoffs for CLT and PAI-1 were determined by 10 log-transformed values.
