Figure 2. Pressure pain detection thresholds.

Figure 2

The horizontal axis shows all six dermatomes, the vertical axis shows pressure pain detection thresholds (pPDT) in kPa. The difference between study groups and all six dermatomes for pPDT is significant (F = 3.75, p<0.0001). Results are means with 95% CI. ‘control’ is healthy control group, ‘moderate’ is moderate chronic pancreatitis group and ‘severe’ is severe chronic pancreatitis group.
