In order to have a sufficient number of patients with each symptom to perform the latent class analyses, the MSAS symptoms that occurred in at least 40% of the patients were identified. This criterion was selected to provide assurance that sufficient information was available to identify classes that were not sample-specific, due to infrequent reports of symptoms. A total of 25 out of 32 symptoms from the MSAS occurred in >40% of the patients.
The 3-to-3-class solution was selected because the BIC was smaller than the 2-to-2-class solution.
Note. LL = log-likelihood; AIC = Akaike Information Criterion, BIC = Bayesian Information Criterion.
