Normal: Reflects samples within normal limits; TA: Tubular adenoma; TVA: Tubulovillous adenoma; HP: Hyperplastic polyp; SSL: Sessile Serrated lesion; dSSL: Dysplastic sessile serrated lesion; TSA: Traditional serrated adenoma; Malignancy: Encompasses cancerous findings; Inadequate sample; Samples insufficient for histological assessment, for example, acellular samples or those with only faecal matter; Lost: Reflects samples that were lost in the handling process and were not received for histopathological assessment.
