 Influence of disease activity on the lipid levels

Increase in disease activity parameterLipidsAbsolute change (mmol/l)Relative decrease (%)p Value
Atherogenic index, ratio of total cholesterol (TC) to high-density lipoprotein cholesterol (HDLc); BASDAI, Bath Ankylosing Spondylitis Disease Activity Index; BASFI, Bath Ankylosing Spondylitis Functional Index; BASG, Bath Ankylosing Spondylitis Global Score; CRP, C reactive protein; ESR, erythrocyte sedimentation rate.
Influence of disease activity parameters on lipid levels, calculated using multilevel regression analyses correcting for age, sex and repeated measurements within subjects.
