After removing studies that did not specifically separate rectal tumors from left‐sided tumors, the prevalence among left‐sided colon tumors did not change substantially from the original analyses (RAS: 36.4% vs 32.4%, KRAS: 34.7% vs 35.8%, BRAF: 4.4% vs 4.3%). Here, BRAF is linked to rectal neoplasm.
