  1. Data in bold significant
  2. PUFAs were expressed as molar proportions (mol %) of total fatty acids. The multivariate linear and logistic regression models were adjusted for age, education (high school or lower, college or above), smoking history, alcohol use history, and treatment (acitretin, methotrexate, phototherapy, and biologics)
  3. β β-coefficient, CI confidence interval, OR odd ratio, PASI Psoriasis Area and Severity Index, PUFAs polyunsaturated fatty acids
