Table 3. Pairwise comparisons of the materials showing the mean difference between disinfection and no disinfection, P value and 95% confidence interval of mean difference at one week storage.

Material	Mean difference	P value	95% CI
ELF	0.014	.208	(−0.008, 0.036)
ELR	0.038	.001	(0.016, 0.060)
HR	0.003	.787	(−0.019, 0.025)
LF	0.010	.368	(−0.012, 0.032)
LR	0.013	.243	(−0.009, 0.035)

ELF = Extra light fast set, ELR = Extra light regular set, HR = Heavy rigid regular, LF = Light fast set, LR = Light regular set.
