Abstract: Several natural history studies on primary progressive multiple sclerosis (PPMS) patients detected a consistent heterogeneity in the rate of disability accumulation. To identify subgroups of PPMS patients with similar longitudinal trajectories of Expanded Disability Status Scale (EDSS) over time. All PPMS patients collected within the MSBase registry, who had their first EDSS assessment within 5 years from onset, were included in the analysis. Longitudinal EDSS scores were modeled by a latent class mixed model (LCMM), using a nonlinear function of time from onset. LCMM is an advanced statistical approach that models heterogeneity between patients by classifying them into unobserved groups showing similar characteristics. A total of 853 PPMS (51.7% females) from 24 countries with a mean age at onset of 42.4 years (standard deviation (SD): 10.8 years), a median baseline EDSS of 4 (interquartile range (IQR): 2.5–5.5), and 2.4 years of disease duration (SD: 1.5 years) were included. LCMM detected three different subgroups of patients with a mild ( n = 143 16.8%), moderate ( n = 378 44.3%), or severe ( n = 332 38.9%) disability trajectory. The probability of reaching EDSS 6 at 10 years was 0%, 46.4%, and 81.9% respectively. Applying an LCMM modeling approach to long-term EDSS data, it is possible to identify groups of PPMS patients with different prognosis.

Abstract: Bokermannohyla Faivovich, Haddad, Garcia, Frost, C bell & Wheeler (2005) is a Brazilian treefrog genus currently composed of 32 species (Brandão et al. 2012 Leite et al. 2012 Frost 2015). The genus comprehends four, putatively monophyletic, species groups: B. circumdata, B. claresignata, B. martinsi, and B. pseudopseudis (sensu Faivovich et al. 2005). The B. pseudopseudis group includes nine species: B. alvarengai (Bokermann 1956), B. flavopicta Leite et al. 2012, B. ibitiguara (Cardoso 1983), B. itapoty Lugli & Haddad 2006a, B. oxente Lugli & Haddad 2006b, B. pseudopseudis (Miranda-Ribeiro 1937), B. sagarana Leite et al. 2011, B. sapiranga Brandão et al. 2012, and B. saxicola (Bokermann 1964).
