Summarized a variety of diagnostic results in published case reports. Diagnostic approaches include EEG/EMG/SFEMG, NCS, RNS, image examinations, serological autoantibodies, CK, ALT/AST, and CSF. White blocks mean this examination has not been mentioned in case reports; green blocks represent negative results; red blocks represent positive results. ALT indicates alanine aminotransferase; AST, aspartate aminotransferase; CK, creatine kinase; CSF, cerebrospinal fluid; EEG, electroencephalograph; EMG, electromyograph; ICI, immune checkpoint inhibitor; NAEs, neurological adverse events; NCS, nerve conduction study; RNS, repetitive nerve stimulation; SFEMG, single-fiber electromyography.
