PT, prothrombin time; aPPT, activated partial thromboplastin time; Fib, fibrinogen; INR, international normalized ratio; CRP, c-reactive protein; PCT, procalcitonin; R, correlation coefficient; B, slope of the regression (also called regression coefficient). CI stands for 95% confidential intervals.
