Considering data shown in Figure 1 and in order to find the number of C9orf72 hexanucleotide repeats that may better distinguish between COVID-19 and ALS patients, we conducted univariate logistic regression analysis at each repeat length >8 repeat units (Figure 2) and found that patients hospitalized for COVID-19 had an odds ratio (OR) of 2.82 (p = 0.06) of having more than 10 repeats, when compared to the ALS patients. This evidence concerns the gene C9orf72 and COVID-19.
