Analyses by linear regression. Model 1 adjusted for ongoing symptoms due to recent relapse. Model 2 further adjusted for age, sex, multiple sclerosis phenotype, socioeconomic status and clinically significant fatigue.
Results in boldface denote statistical significance (p < 0.05).
Abbreviations: DHQ, Diet Habits Questionnaire.
Analyses for DHQ score vs. disability in model 1 includes 1,322 people, thus excluding 24 people with missing data. Model 2 includes 1,235 people, thus excluding 111 people with missing data.
Analyses for meat consumption vs. disability in Model 1 includes 1,323 people, thus excluding 23 people with missing data. Model 2 includes 1,236 people, thus excluding 110 people with missing data.
Analyses for dairy consumption vs. disability in Model 1 includes 1,319 people, thus excluding 27 people with missing data. Model 2 includes 1,232 people, thus excluding 114 people with missing data.
