In the article “Neurofilament light chain: A prognostic biomarker in amyotrophic lateral sclerosis” by C.-H. Lu et al. (Neurology® 2015;84:2247–2257), there is an omission in the Study Funding section, which should read: “A.M. is funded by the Medical Research Council (MR/M015882/1).” The authors regret the omission.
