Differences in mutant-allele heterogeneity (MATH) scores and variant allele frequency (VAF) clusters identified from matched formalin-fixed paraffin-embedded (FFPE) and frozen gastro-oesophageal tumours. Histogram illustrating (A) differences in MATH scores between FFPE and frozen tumour samples—11 out of 14 FFPE tumours had higher MATH scores when compared with the corresponding frozen tumours (p < 0.001 Wilcoxon rank test); and (B) VAF clusters identified from FFPE and frozen samples.
