To the Editor We read with great interest the article by Rosenbohm and colleagues.1 They conducted a case-control study and reported that retinol-binding protein 4 had an inverse association with both risk for amyotrophic lateral sclerosis (ALS) and disease prognosis. Although we agree with the relevance of the reported results and their interpretation, we would like to comment on 2 issues that might also correlate with these findings.
