Fig. 4From: The role of FoxP3+ regulatory T cells and IDO+ immune and tumor cells in malignant melanoma – an immunohistochemical studyMean counts of FoxP3+ Tregs (a) and IDO+ stromal immune cells (b) analyzed by hotspot analysis. FoxP3+ Tregs were analysed from 183, and IDO+ stromal immune cells from 193 melanocytic samples. The data represents mean ± SD. Statistically significant differences between the groups are shown in brackets (Kruskal-Wallis test). *P < 0.05, **P < 0.01, ***P < 0.001Back to article page
