Comprehensive studies of fibrinolysis in non-small cell lung carcinoma have been limited,
and assignment of patients to high/low prognosis groups based on arbitrary cut-offs utilizing
fibrinolytic measurements is unstandardized. This study was performed in 166 patients to
examine the effects of cut-off values determined in three ways. Model 1 assigned patients to
one of three equal groups (low, medium, high) based on fibrinolytic measurements made at
diagnosis, Model 2 divided patients into low/high groups using median values, and Model 3 …
