Platelet, apolipoprotein A-1, apolipoprotein B, and the interval were calculated as metrological data, and others are counting data. NLR: Neutrophil-lymphocyte ratio; DTAV: Distance of tumor from the anal verge; TL: Tumor length; TCE: Tumor circumferential extent; NT: Neoadjuvant therapy; PLT: Platelet; ApoA1: Apolipoprotein A-1; ApoB: Apolipoprotein B; MRF: Mesorectal fascia; CEA: Carcinoembryonic antigen.
