Criteria and parameters of metabolic syndrome in pre-operative and post-operative patients suffering from AI.

The percentages of pre-operative and post-operative patients with pathological alterations (%) and mean ± SD data of the analyzed parameters are shown. The P-values calculated by the Mann–Whitney U-test (for waist circumference, plasma HDL-cholesterol, plasma TG, blood pressure, fasting plasma glucose) or thy Chi-square test (for frequency of central obesity, hypo-HDL-cholesterolemia, hypertriglyceridemia, hypertension, hyperglycemia, and metabolic syndrome) are indicated. Significant P-values (<0.050) are in boldface.
