Table 4. Pairwise comparisons of the materials showing the mean difference between disinfection and no disinfection, P value and 95% confidence interval of the mean difference at 2-week storage.

Material	Mean difference	P value	95% CI
ELF	0.036	< .001	(0.018, 0.053)
ELR	0.017	.057	(−0.001, 0.034)
HR	0.015	.093	(−0.003, 0.032)
LF	0.040	< .001	(0.022, 0.057)
LR	0.009	.312	(−0.008, 0.026)

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