From: Insights on diagnosis and therapeutic decision-making patterns for multiple sclerosis treatment: cross-sectional opinion survey results from Japanese neurologists

Question and answer Overall (n = 205) Sub-group by the number of MS patients under care P value
Group 1: 1–3 patients (n = 69) Group 2: 4–9 patients (n = 58) Group 3: ≥10 patients (n = 78) Group comparison* Trend test
Question: Can dissemination in time and space be determined for the purpose of diagnosing RRMS in the presence of 1 clinical attack with a single MRI scan?
Yes, n (%) 177 (86.3) 54 (78.3) 51 (87.9) 72 (92.3) 0.152a 0.015b 0.391c 0.014
  1. RRMS relapsing remitting multiple sclerosis, MS multiple sclerosis, MRI magnetic resonance imaging
  2. *Percentages were compared in groups of two using the chi-square test, and the corresponding P values are indicated for the following comparisons: a: Group 1 vs. Group 2, b: Group 1 vs. Group 3, c: Group 2 vs. Group 3
  3. The trend across the three groups was tested using the Cochran-Armitage test
