^aBaseline characteristics were defined as general patient demographics at diagnosis; median age in years at date of diagnosis, gender, symptoms at diagnosis, ASA physical status classification grade, and history of primary sclerosing cholangitis. ^bCharacteristics as described in preoperative imaging reports were cholecystitis, cholecystolithiasis, the presence of gallbladder polyps, pathological regional or distant lymph nodes, and invasion of the liver or other organs by the tumour and T stage. When unknown or not derivable from imaging, T stage was defined as Tx
