[EX Q]: Question: Is low caregiver health literacy associated with higher pediatric emergency department use and nonurgent visits?
Answer: Over half of caregivers presenting with their children to the ED have low health literacy. Low caregiver health literacy is an independent predictor of higher ED use and use of the ED for nonurgent conditions. In children without a chronic illness, low health literate caregivers had more than 3 times greater odds of presenting for a nonurgent condition than those with adequate health literacy.

[EX Q]: Question: Do a qualitative study of the background and in-hospital medicolegal response to female burn injuries in India?
Answer: The similarities between accident and intention cluster so tightly as to make them challenging to distinguish, especially given women's understandable reticence to describe burns as non-accidental. The contested status of forensic evidence and a reliance on testimony means that only a minority of cases lead to conviction. The emphasis should be on improving documentation, communication between service providers, and public understanding of the risks of burns.
[EX A]:
yes
