*3.2. Univariate Analysis*

The number of lesions was the only clinical parameter that was significantly predictive for survival in this population (*p* = 0.006) (Table 2). Furthermore, analysis of the [18F]FDG-PET features showed SUVmax and SUVpeak to be significantly predictive for survival (*p* = 0.004 and 0.006, respectively) (Figure 2). Hazard ratios (HRs) were 1.16 per unit increase for SUVmax and 1.20 per unit increase for SUVpeak in univariate analysis.
