I want to know the answer to the following question:
What does not rule out infection?
All the background I'm provided with is that "The review showed that the most useful finding is an increase in the level of pain [likelihood ratio (LR) range, 11-20] makes infection much more likely, but the absence of pain (negative likelihood ratio range, 0.64-0.88) does not rule out infection (summary LR 0.64-0.88).". Is that enough to answer the question?
Answer: yes
