Reliability of each measurement platform in the four-modality latent variable SEM measurement model, and its correlation to the latent variable (true relative frequency of Faecalibacterium)

	Four- modality measurement model
	Sanger	454_V1V3	454_V3V5	qPCR
Reliability	0.819	0.857	0.912	0.441
(95% CI)	(0.689, 0.907)	(0.774, 0.917)	(0.865, 0.963)	(0.303, 0.553)
Correlation to the latent variable	0.905	0.926	0.955	0.664
(95% CI)	(0.830, 0.952)	(0.880, 0.958)	(0.930, 0.981)	(0.550, 0.744)

The 95 % confidence intervals are obtained using bootstrap resampling with 100 replications [24].
