Development and validation of a prediction model for estimating 24-Hour Urinary Sodium Excretion using spot urine samples in adult patients.

Unlabelled: The measurement of urinary sodium excretion provides valuable information about an individual's sodium balance and can help in the management of various medical conditions. However, the collection of 24-hour urine samples is subject to errors. Spot urine sodium (uNa) measurements are a reliable alternative to 24-hour urine collections for estimating urinary sodium excretion.
