Fig. 1From: Inhibition of SIRT6 potentiates the anti-tumor effect of doxorubicin through suppression of the DNA damage repair pathway in osteosarcomaStatistical and survival analysis according to the immunohistochemical expression of SIRT6 in osteosarcoma. a Immunohistochemical expression of SIRT6 in human osteosarcoma tissue. b Receiver operating characteristic curve analysis to determine a cut-off point of immunohistochemical expression of SIRT6. The cut-off point was determined as the point with the highest area under the curve (AUC), indicated by the arrow. c Kaplan-Meier survival analysis according to SIRT6 expression for overall survival and relapse-free survival in 37 osteosarcoma patientsBack to article page
