Serum levels of cholesterol and lipoprotein subfractions change during illness or stress. However, authors didn't comment on the postoperative course of these patients. There is one hint in the study for this. Diabetic patients are more likely to have post-operative complications. Although, there were more diabetic patients in the study, p-values were not statisticaly significant due to increased spread in the values form diabetic patients. It is quite possible that this increased variability may be due to complicated post-op course. I understand that this is a mere speculation, but authors have left a lot of space for speculation. May be auhtors would do another study to include the post-operative course as another viriable in the analysis of data.
