CRP and Hyponatremia: A logistic regression analysis revealed that the patients with hyponatremia based on TASNa more likely to be female [OR 3.25 (95% CI 1.25–8.46), P = 0.016], and to have higher serum glucose [OR 1.39 (95% CI 1.24–1.56), P < 0.001], higher SBP [OR 1.06 (95% CI 1.02–1.10), P = 0.001] and higher CRP [OR1.09 (95% CI 1.04–1.15), P < 0.001].
