Fig. 3From: Determination of GP88 (progranulin) expression in breast tumor biopsies improves the risk predictive value of the Nottingham Prognostic IndexOverall Survival by GP88 score within the three NPI groups. Using the NPI score calculated for each of the 508 ER+ IDC cases, Kaplan-Meier plots were fitted for OS functions for the patients within each NPI grouping (a-GPG <3.4, b-MPG 3.4–5.4, c-GPG >5.4) stratified by their GP88 tissue expression using the IHC scores of <3+ in black solid line and 3+ in red dashed lineBack to article page
