In the published article, there was an error in Figure 4 as published. Antigen category of “Overexpressed Antigens” was mislabeled. The corrected Figure 4 and its caption appear below.

Figure 4 Evaluation of tumor-specificities of yTILs produced with IL-2 alone or CPI. yTILs were stained with pooled tetramers loaded with 156 unique HLA-A2-restricted epitopes. (A) shows the number of tumor antigens yTILs from each patient had across conditions with anti-CTLA-4 group having statistically significant more specificities than alone (P value = 0.0156), while the anti-PD-1 group is not significant (P value = 0.938). (B) shows the sum of the estimated frequencies of tumor antigens across conditions. The sum est freq of the anti-CTLA-4 group is not statistically significant (P value = 0.2969). The individual specificity frequencies for each tumor antigen across 3 antigen categories are represented with a heatmap (C). “X” indicates value of 54.17%. Wilcoxon test was applied to compare paired data sets. “ns” = not significant; “*” represents the p value which is listed in the image description.
In the published article, there was also an error in Table 2 as published. Column heading of “%CD8+ of CD3+” was mislabeled and English decimal, “.” was not used. The corrected Table 2 and its caption appear below.
