Fit Indices of CIPD With Five Profiles.

Model	Classes	AIC	BIC	Entropy	N_min	BLRT
1	2	8804	8873	0.799	0.324	0.01
1	3	8734	8829	0.789	0.216	0.01
1	4	8654	8775	0.728	0.193	0.01
1	5	8493	8640	0.796	0.119	0.01

Note. The table indicates that the CIDP model with five latent profiles exhibits lower AIC and BIC values, and a high entropy value, resulting in improved differentiation between profiles. The information criteria used are AIC (Akaike Information Criterion) and BIC (Bayesian Information Criterion). The BLRT-p (Bootstrapped Likelihood Ratio Test) was employed for comparison. Values highlighted in bold indicate the optimal model based on criteria used.
