There is LITTLE DATA supporting SNM for urinary retention.

• A. A lot of data
• B. Moderate data
• C. No data
• D. LITTLE DATA

Answer: (D)

The main idea here is matching the described level of evidence to the option that expresses that exact quantity. If the claim is that there is only a small amount of evidence, the descriptor must be those words that convey limited data. Saying there is a lot of data would contradict the statement; saying there is no data would imply zero evidence, which isn’t what’s stated; saying there is moderate data would imply more than what’s described. So the best fit is the option that says LITTLE DATA. This means there are only sparse or limited studies on sacral neuromodulation for urinary retention, and conclusions are tentative pending more research.
