Figure 2

Boxplot, urinary concentrations of HP and LP: each box shows the median, quartiles and extreme values. Group 1a (OSCC with mandibular bony infiltration, n=12), group 1b (samples of patients of group 1a >6 months after successful treatment), group 2a (OSCC without mandibular bone infiltration, n=8), group 2b (samples of patients of group 2a >6 months after successful treatment), group 3a (recurrence of OSCC, n=8), group 3b (samples of patients of group 3a >6 weeks later, symptoms unchanged) and group 4 (control group, patients without disease n=74). Lines mark HP_max (95 nmol mmol⁻¹ creatinine) and LP_max (20 nmol mmol⁻¹ creatinine). In regard to groups 1a and 2a, the LP_max line separates the LP values completely. (○) Values of patients that significantly exceeded the normal range in the recurrence group. While values in groups 1b and 2b approach the normal range as given by group 4 values exceeded it in groups 3a and 3b.
