Diagnosis of Creutzfeldt-Jakob disease by measurement of S100 protein in serum: prospective case-control study

An authors’ error occurred in this paper by Markus Otto and colleagues (21 February, pp 577-82). In table 4 the median values of serum concentrations of S100 protein were incorrect for some diagnoses. For the diagnosis of multi-infarct dementia the median value should have been 104 [not 393]; the median value for progressive dementia should have been 191 [not 529]; the median for amyotrophic lateral sclerosis should have been 56 [not 179]; and the median for chronic encephalopathy should have been 77 [not 47].
