The prognostic values of intratumoral pDCs combined with IL-17+ cells (a), with Treg cells (b), and with Treg cells and IL-17+ cells (c) in HCC patients. The predictive ability for OS (d) and TTR (e) of pDCs, pDCs and IL-17+ cells, pDCs and Treg cells, and pDCs, IL-17+, and Treg cells compared with that of other clinical parameters by receiver operating characteristic curves for 224 HCC patients. The area under the curve with 95% confidence interval is shown
