Correlations between neurological scores and serum sodium levels. Clinical neurological manifestations showed (A) an inverse correlation with minimum sodium level (Spearman's correlation coefficient −0.59), and positive correlations with (B) changes in absolute sodium levels (Spearman's correlation coefficient 0.58) and (C) percent changes in serum sodium levels (Spearman's correlation coefficient 0.60). All p values were less than 0.001.
