*p Values from Fisher's exact test, indicating association between individuals polyps by site (right vs left).
BSSA/P/L, borderline sessile serrated adenoma/polyp/lesion; HP, hyperplastic polyp; IS, ignoring SCRC status; ND-SP, non-dysplastic serrated polyp; SCRC, synchronous colorectal cancer; SSA/P/L, sessile serrated adenoma/polyp/lesion.
