[EX Q]: Question: Does an ultrasound-guided fascia iliaca catheter technique impair ambulatory ability within a clinical pathway for total hip arthroplasty?
Answer: BMI affects postoperative ambulation outcome after hip arthroplasty, whereas the type of regional analgesic technique used does not. An ultrasound-guided FIC technique offers similar analgesia with fewer side effects when compared with ITM.
[EX A]: no

[EX Q]: Question: Is nonadherence with ambulatory saliva sampling associated with biased salivary testosterone estimates?
Answer: The results suggest that common ambulatory nonadherence with scheduled saliva sampling is associated with biased salivary testosterone estimates. They will inform further studies estimating salivary testosterone with ambulatory saliva-sampling designs and highlight the relevance of strategies to improve or confirm adherence, beyond routinely used instructions.
[EX A]: yes

[EX Q]: Question: Do adenomas at resection margins influence the long-term development of pouch polyps after restorative proctocolectomy for familial adenomatous polyposis?
Answer: Incidence of pouch adenomas was low. There was no correlation between adenomas in the resection margins and the development of pouch adenomas.
[EX A]:
no
