(A) Predicted vs. measured immune cell proportions in PBMC (dataset 1 (Zimmermann et al., 2016), dataset 2 (Hoek et al., 2015)) and whole blood (dataset 3 (Linsley et al., 2014)); predictions are …
Heatmaps show (A) the Pearson R correlation and (B) the root mean squared error, between the cell fractions predicted by each method and the experimentally measured fractions (dataset 1 [Zimmermann …
Pearson R correlations are shown as in Figure 2—figure supplement 1A, showing here for each method its original result and the result if the predicted proportions are then renormalized by the mRNA …
Comparison of the predictions as done in Figure 2—figure supplement 1A, for different variations from EPIC: (1) full EPIC method; (2) EPIC if the gene expression reference profiles are scaled a …
Results are shown similarly than in Figure 2—figure supplement 1A. Here, we present for various cell fraction prediction methods the results considering all the immune cell types in the gene …
(A) Comparison of EPIC predictions with our flow cytometry data of lymph nodes from metastatic melanoma patients. (B) Comparison with immunohistochemistry data from colon cancer primary tumors (Becht…
Same as Figure 3 but based on reference profiles built from the single-cell RNA-Seq data of primary tumor and non-lymphoid metastatic melanoma samples from Tirosh et al. (2016). (A) Comparison with …
(A) Pearson R correlation and (B) RMSE between the cell fractions predicted and the experimentally measured fractions (from flow cytometry of lymph nodes from metastatic melanoma patients (this …
(A) Pearson correlation R-values between the cell proportions predicted by EPIC and ISOpure and the observed proportions measured by flow cytometry or single-cell RNA-Seq (Tirosh et al., 2016), …
(A) Pearson R correlation and (B) root mean squared error between the cell fractions predicted by each method and the experimentally measured fractions (from flow cytometry (this study), colorectal …
(A) Comparison directly of all cell types together. When a cell type could not be predicted by a given method, this cell type is absent from the subfigure. (B) Comparison per cell type for …
Observed values are in number of cells/mm2. Correlation values are available in Figure 5—figure supplement 1.
(A) Comparison directly of all cell types together. When a cell type could not be predicted by a given method, this cell type is absent from the subfigure. (B) Results for MCP-counter, splitting the …
The predictions are compared to the observed cell proportions. ESTIMATE returns a score of global immune infiltration and thus the sum of all observed immune cells has been taken for the comparison. …
The proportions of Thelper and Treg cells predicted by EPIC and CIBERSORT are compared to the proportions observed in the bulk samples reconstructed from the single-cell RNA-seq data from melanoma …
(A) For all immune cell types in the blood datasets (dataset 1: Zimmermann et al. 2016; dataset2: Hoek et al. 2015; dataset 3: Linsley et al. 2014). (B) and (C) in the tumor datasets, based on all …
Only markers of cell types present in the respective reference gene expression profiles are used.
