Cox's proportional hazards regression model. Adjusted to tumour stage, tumour localization, tumour entity, tumour resection and expression of Hiwi for 65 patients with STS in 100 months. Cutoffs for expression of Hiwi were >1.5 ag (high), >0.05 to ⩽1.5 ag (medium) and ⩽0.05 ag mRNA (low) standardized to ag HPRT expression.
