The sodium trigger for treatment was defined as pretreatment sodium level, with response and overcorrection defined as increments of \u22655 and &amp;gt;10 mmol\/L after 24 h, respectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>This study enrolled 364 children with BM (age: &amp;lt;16 years; 215 boys). Hyponatremia occurred in 62.1% of patients, among whom 25.7% received sodium-altering therapies; 91.4% of those individuals had moderate\/severe hyponatremia. Monotherapy was the most common initial hyponatremia treatment. After 24 h of treatment initiation, 82.4% of the patients responded.
