Q: Given an abstract, indicate which of the provided candidate titles (Option1 and Option2) best describes it (respond with the text of the title, not option1/2).
Abstract: The urine urea nitrogen/urine creatinine excretion ratio (UUN/UCr) of a "spot" urine specimen obtained approximately 5 hours after the last meal of the day can be used to accurately calculate the urinary urea excretion for the previous 24-hour period. Because UUN excretion is largely determined by dietary intake of protein nitrogen, this method can be used to estimate dietary protein intake for the previous 24-hour period. Strategies for using this simple method for inexpensively and continuously monitoring dietary protein intake are discussed.
Which is the apt title for the abstract? option1: Simple method for monitoring 24-hour urinary urea nitrogen excretion. option2: Impact of myelography on the radiotherapeutic management of malignant spinal cord compression.
A:
Simple method for monitoring 24-hour urinary urea nitrogen excretion.
