Fig. 5From: Soluble Periostin is a potential surveillance biomarker for early and long-term response to chemotherapy in advanced breast cancerEffects of baseline levels of POSTN on its early monitoring performance. A, the correlation between baseline levels of POSTN and its change rate in cases with partial response (n = 33). B, comparison of change rate of POSTN in partial response cases with baseline above (n = 24) and below (n = 9) the cutoff value. C, comparison of consistent rate of POSTN in cases with partial response cases with baseline above and below the cutoff value. Dotted lines indicated a 20% decrease of markers. D, agreement between radiographic response and POSTN’s response in 42 cases with baseline above the cutoff valueBack to article page
