Table 3 Comparison of tumor cell PD-L1 expression for TMA with ‘whole section’ (cohort-2, n = 237)

From: Programmed death-ligand 1 expression influenced by tissue sample size. Scoring based on tissue microarrays’ and cross-validation with resections, in patients with, stage I–III, non-small cell lung carcinoma of the European Thoracic Oncology Platform Lungscape cohort

  1. In green (upper right of diagonal): underestimated cases, in red (lower left of diagonal): overestimated, in blue (last line of the table): cases not evaluable by TMAs but evaluable by Whole Sections method, or vice versa
  2. Bold numbers represent the cases were complete agreement is achieved in the PD-L1 score between whole section and tumor microarray methods
