Table 1 Anthropometric, nutritional and biochemical variables for total obese patients, and according to oxidized-LDL (Ox-LDL) levels (lower or higher than the median value observed for total patients, 39.2 U/l)

From: Bilirubin is independently associated with oxidized LDL levels in young obese patients
