CXCL8 and episodic ataxia type 2: In detail, male CAPA patients had significantly lower IL-8 (p = 0.0001) and caspase-3 (p = 0.0004) serum levels compared with COVID-19 control patients, whereas significantly lower levels in cases compared with controls in female patients were observed only for IL-8 (p = 0.0409), potentially due to limited sample numbers.
