Figure 4. COVID-19 Symptoms and PCR Positivity Duration by DMT.

Figure 4

Duration of COVID-19 symptoms and duration of COVID-19 PCR positivity were grouped by DMT efficacy (none/other, low, mid, and high). (A) Symptom duration in days is indicated on the x axis, and DMTs grouped by efficacy are on the y axis. There were no significant differences in symptom duration based on DMT efficacy with one-way analysis of variance. A number of patients contributing to each group for symptom duration were 2 none/other, 5 low efficacy, 2 mid efficacy, and 10 high efficacy. (B) Duration of PCR positivity in days is indicated on the x axis, and DMTs grouped by efficacy are on the y axis. There was a significant association of DMT efficacy with post hoc analysis (Bonferroni) demonstrating a significant difference between high-efficacy DMT vs none/other DMT with regard to duration of PCR positivity. A number of patients contributing to each group for PCR positivity duration were 4 none/other, 5 low efficacy, 1 mid efficacy, and 9 high efficacy. Error bars indicated SEM and are not shown in samples where n = 1. Significance (p < 0.05) is indicated by *. COVID-19 = coronavirus disease 2019; DMT = disease-modifying therapy.
