Correlation Matrix of Repeatability (Intra-Class Correlation) for Nociceptive Withdrawal Threshold Using the Randall-Selitto Test

	Plantar fore paw		Dorsal fore paw		Plantar hind paw		Dorsal hind paw
	Day 1	Day 2	Day 1	Day 2	Day 1	Day 2	Day 1	Day 2
Day 1	0.471 (0.002)	0.509 (0.048)	0.307 (0.035)	0.578 (0.026)	0.417 (0.005)	0.254 (0.215)	0.047 (0.346)	0 (0.910)*
Day 2		0.405 (0.009)		0.255 (0.058)		0.363 (0.009)		0.230 (0.078)

For each body part, the diagonal values are the intra-day repeatability and the upper diagonal values are the inter-day repeatability (numbers in parentheses represent significance level from the one-way ANOVA). Repeatability underlined is significant (p<0.05) after correcting for multiple testing using Bonferroni test.

^*The between-rats estimated variance from the ANOVA method was negative.
