Among patients who developed hyponatremia, the median C-reactive protein value was notably higher (4.3 mg/dL [95% CI, 1.2-10.3 mg/dL]) compared with those without hyponatremia (1.3 mg/dL [95% CI, 0.3-5.3 mg/dL]) (to convert to milligrams per liter, multiply by 10.0). This evidence concerns the gene CRP and Hyponatremia.
