Kaplan-Meier curves for overall survival regarding the four most represented histologies. Red lines indicate patients in the control cohort while green lines indicate patients in the hyponatremia cohort. Thick lines indicate raw survival curves while thin lines indicate adjusted survival curves. Patients in the control cohort had higher overall survival compared to patients in the hyponatremia cohort in colorectal cancer (CRC, panel A), non-small cell lung cancer (NSCLC, panel B) and breast cancer (BC, panel C). In gastroesophageal cancer (GEC, panel D), adjusted model indicates that patients in the hyponatremia cohort had a better prognosis than patients in the control cohort.
