Distribution of mismatch repair-deficient and proficient endometrial cancers with respect to sequencing findings. Mismatch repair deficiency is assessed by immunohistochemical expression of MLH1, MSH2, MSH6, and PMS2. The x-axis shows the number of insertion and deletion events in mononucleotide repeats per megabase per case by sequencing, rounded to the nearest integer. Each bar represents the number of mismatch repair-deficient or -proficient endometrial cancers with that number of events
