Table 2.

Results from equivalence testing across visit types. Equivalence is claimed with 5% significance (*) when the 90% confidence interval on the mean ratio is completely contained within the equivalence bounds of [0.80, 1.25]. For comparison, 80% confidence intervals are displayed for a test of equivalence with 10% significance (#) for those not significant at the 5% level.

Instrument	ICC	Asymmetric 90% Conf Int on ratio	Asymmetric 80% Conf Int on ratio
ALS-CBS	0.50	[1.00, 1.11] *
COWAT	0.34	[0.90, 0.99]*
CNS-LS	0.79	[0.94, 1.09] *
FBI-ALS	0.54	[0.72, 1.14]	[0.76, 1.08]
WVFI	0.76	[0.95, 1.32]	[0.99, 1.27]
MMSE_TICS (%)	^b	[0.84, 0.93] *
ALS-CBS-CG (%)^a	0.79	[0.95, 1.00] *

A constant value of 1 was added to accommodate the 0s in log transformed values.

The ICC could not be estimated due to ill-conditioning of the covariance matrix of the random effects.
