Analyses by linear regression. Model 1 adjusted for baseline and 2.5‐year ongoing symptoms due to recent relapse and baseline P‐MSSS. Model 2 further adjusted for age, sex, multiple sclerosis (MS) phenotype, socioeconomic status, and baseline clinically significant fatigue.
Results in boldface denote statistical significance (p < 0.05).
Abbreviations: DHQ, Diet Habits Questionnaire; P‐MSSS, Patient‐deterimined MS Severity Score.
Analyses for DHQ score vs. disability in Model 1 includes 1,291 people, thus excluding 55 people with missing data. Model 2 includes 1,207 people, thus excluding 139 people with missing data.
Analyses for meat consumption vs. disability in model 1 includes 1,290 people, thus excluding 56 people with missing data. Model 2 includes 1,206 people, thus excluding 140 people with missing data.
Analyses for dairy consumption vs. disability in Model 1 includes 1,281 people, thus excluding 65 people with missing data. Model 2 includes 1,201 people, thus excluding 145 people with missing data.
