Table 2. Item-level correlations.

The correlations of the six items were determined by calculating the relevant correlation coefficient based on the PGIS anchor (n = 59). Cut-offs applied were ‘weak correlation’: r < 0.30; ‘moderate correlation’: 0.30 ≤ r < 0.50; and ‘strong correlation’: r ≥ 0.50.

Item	Type of correlation coefficient	r
1–Bleeding	Point-biserial	0.266
2–Weeping	Point-biserial	0.431
3–Ulcers/sores	Point-biserial	0.633
4–Itching (severity)	Polyserial	0.457
5–Pain (severity)	Polyserial	0.442
6–Burning (severity)	Polyserial	0.468
