Comparison of lipid profile between opium user and non-user at the first of phase of PERSIAN cohort study. Lipid profile is presented with the mean—black bars—and standard deviation—white error bars—in mg/dL. The normal and abnormal ranges of lipid profiles are colored in green and red background. The border of the normal and abnormal HDL between the male and female subjects was also colored as purple background. The p-values came from a linear multivariable model that all variables having a correlation with lipid profile in univariate analysis with a p-value less than 0.2, were added to it. The p-value of the opium use variable in this model was reported as the Adjusted p-value.
