ABSTRACT=Objective: Investigate the relationship between admission serum potassium (K+) levels and the Island Sign (IS) presence in Hypertensive Intracerebral Hemorrhage (HICH) patients' cranial CT scans, considering potential non-linear patterns.

Methods: Analyzed data from 330 HICH patients, using logistic regression and curve-fitting models to explore associations.

Results: Discovered a non-linear correlation, with an inflection point at approximately 3.54 mmol/L. Lower serum K+ levels upon admission associated with higher IS incidence.

Conclusions: Suggests maintaining physiological serum K+ levels may mitigate IS risk in HICH patients, highlighting its potential significance.
