TC: total cholesterol; HDL: high-density lipoprotein; LDL: low-density lipoprotein; APTT: activated partial thromboplastin time; PT: prothrombin time; OP: occluded position; AC: anterior circulation; HD: hyperdensity; VR: vascular recanalization; HT: hemorrhagic transformation; END: early neurological deterioration; f: Fisher’s exact test; : the CT value of the high-density PCHD-4 group was higher than that of the PCHD-1 and PCHD-2 groups, but no difference was found between these three subgroups and the PCHD-3 group.
