Fig. 2From: Programmed cell death ligand 1 cut-point is associated with reduced disease specific survival in resected pancreatic ductal adenocarcinomaParametric disease specific survival analysis using the log-logistic distribution to model disease specific survival in the entire cohort (a). Modeling of disease specific survival against PD-L1 expression assessed by percent positive (b) and H-Score (c) survival using a log-logistic distribution demonstrates a substantial association between reduced survival and increased PD-L1 expression. Curves shown are fitted as a function of the regressor representing the 0.9, 0.5, and 0.1 quantilesBack to article page
