From: Effects of disease activity on lipoprotein levels in patients with early arthritis: can oxidized LDL cholesterol explain the lipid paradox theory?

Fig. 4

Ratio of oxidized LDL cholesterol to LDL cholesterol in patients with early arthritis classified in different strata according to their LDL cholesterol level. Data are represented as box plots including median (line inside the boxes) and the percentiles 25, 75 (lower and upper lines of the boxes), and 10 and 90 (endpoints of the lines outside the boxes).
