3.6 Predictive clinical and laboratory parameters for tumor necrosis
Among the various clinical and laboratory parameters assessed for association with TN, using TN as a continuous variable as well as at cut-offs of 90%TN, 94%TN (median TN), type of surgery was predictive at all the above three assessments and male gender at a cut-off of 90%TN. Amputation had a higher risk of poor histological necrosis compared to LSS (OR:2.1, p=0.014) as was male gender (OR:1.9, p=0.01). Details in TABLE 3.
