Fig. 3From: Neurofilament light chain is a promising serum biomarker in spinocerebellar ataxia type 3Associations between serum NfL and disease stages of SCA3. a. For preclinical SCA3, serum NfL concentration is significantly higher in the late preclinical than the early preclinical SCA3. b. Serum NfL concentration is significantly higher in the manifest stage of SCA3 than preclinical SCA3. No significant difference is seen between Stage 1 and Stage 2Back to article page
