BRAF and KRAS mutants in 66 colorectal carcinomas

		CD274 expression
	Total No. 66 (100%) [100%]	Positive 16 (24%) [100%]	Negative 50 (76%) [100%]	P-value

Gene mutation				P < 0.001^a
BRAF mutant	19 (100%) [29%]	14 (74%) [88%]	5 (25%) [10%]
KRAS mutant	27 (100%) [41%]	1 (4%) [6%]	26 (96%) [52%]
Wild type	20 (100%) [30%]	1 (5%) [6%]	19 (95%) [38%]

P-value was calculated by the Fisher’s exact test for CD274 expression. The Bonferroni-corrected P-value for significance was P = 0.017(0.05/3). P < 0.001 (BRAF mutant vs KRAS mutant), P < 0.001 (BRAF mutant vs wild type).
