Practice questions
- In the retrospective total knee arthroplasty study, which pair of criteria defined range-of-motion success at 2 weeks and 6 weeks, respectively?
- A patient receiving apixaban after primary total knee arthroplasty has not yet achieved 90° flexion at 2 weeks. Which conclusion best reflects the supplied study?
- In the TKA study, what was the reported odds ratio for meeting the 2-week ROM success threshold with factor Xa inhibitors versus aspirin?
- The reported 95% confidence interval for the 2-week ROM odds ratio comparing factor Xa inhibitors with aspirin was 0.866–1.054. Which interpretation is most appropriate?
- Which statement best summarizes the study's finding about manipulation under anesthesia after TKA?
- Which method was used to classify preoperative nutritional status in the stomach cancer cost study?
- Among 1,102 adults undergoing stomach cancer surgery in the reported Chinese cohort, what proportion was classified as at nutritional risk?
- Which three cost categories together accounted for approximately 70%–75% of total costs in the stomach cancer study?
- A hospital observes that preoperative nutritional status is associated with different treatment costs in a retrospective cohort. Which inference is best supported by the supplied study?
- Which statement about annual medication-cost proportions in the stomach cancer study is accurate?
- Which instrument was used to assess preoperative depression severity in the bariatric-surgery cohort?
- At which reported follow-up times did patients with a preoperative depression diagnosis have significantly greater %EBWL than those without depression?
- Within the bariatric cohort's depression subgroup, which PHQ-9 severity category had significantly greater 1-year %EBWL than the more symptomatic categories?
- Which statement accurately describes the bariatric study's 30-day perioperative complication findings by depression diagnosis or PHQ-9 severity?
- In the depression subgroup of the bariatric cohort, which comparison was associated with higher overall complications and 30-day readmissions?
- How should the association between antidepressant use and fewer reported complications in the bariatric depression subgroup be interpreted?
- Which conclusion about preoperative depression and bariatric surgery is supported by the supplied study?
- Which operations were included in the bariatric-surgery cohort evaluating preoperative depression and antidepressant use?
- In the ureteroscopy study, what age criterion defined the older-patient population?
- Which procedure was studied in association with preoperative tamsulosin use in older adults with ureteral stones?
- Which set of outcomes was reported as more favorable in the preoperative tamsulosin group?
- Which statement best describes the ureteral-dilation finding in the tamsulosin study?
- The tamsulosin group had fewer postoperative complications, but several differences did not reach statistical significance. Which conclusion is most appropriate?
- No treatment-related serious adverse effects were observed in the tamsulosin study. What is the most defensible interpretation?
- Which limitation most directly prevents the retrospective tamsulosin study from establishing that the drug caused the observed procedural differences?
- A clinician asks whether the retrospective tamsulosin report establishes routine preoperative use for all patients undergoing ureteroscopy. Which response best fits the evidence?
