Fig. 2From: TIPE2 acts as a biomarker for GIST risk category and suppresses the viability and invasiveness of GIST cellsStatistical results of TIPE2 expression in GIST tissues and ROC curves curve to assess the diagnostic value of TIPE2 in GIST. a IHC sum scores showed that TIPE2 expression was gradually down-regulated in accordance with GIST risk grades. b IHC sum scores were used to assess the association between TIPE2 expression and the ratio of Ki-67 positive cells. c IHC sum scores showed a significant decrease of TIPE2 expression in high risk GIST tissues. d The ROC curves showed strong separation between low-intermediate risk GIST tissues and high risk GIST tissues, with an AUC of 0.754 (P < 0.001). *P < 0.05; ***P < 0.001Back to article page
