Practice questions
- In the COSMIN review of the 5-repetition sit-to-stand test in lumbar degenerative disorders, what was the pooled test-retest reliability estimate?
- A clinician is reviewing evidence about agreement between different assessors administering the 5R-STS to patients with lumbar degenerative disorders. Which pooled estimate did the systematic review report?
- The pooled weighted mean standard error of measurement reported for the 5R-STS in lumbar degenerative disorders was:
- The 5R-STS had an estimated correlation of 0.53 with the Oswestry Disability Index in patients with lumbar degenerative disorders. How did the review interpret this result for criterion validity?
- In the systematic review, only 40% of predefined hypotheses for construct validity of the 5R-STS were confirmed. Which conclusion did the review draw?
- Which combination best summarizes the measurement-property profile of the 5R-STS in lumbar degenerative disorders reported by the COSMIN review?
- A meta-analysis of unilateral versus bilateral pedicle screw fixation for two-level lumbar degenerative disorders included how many randomized controlled trials and patients?
- For two-level lumbar degenerative disorders, which outcome was significantly better with unilateral rather than bilateral pedicle screw fixation in the cited meta-analysis?
- A surgeon claims that unilateral fixation is proven equivalent to bilateral fixation for all clinically important outcomes in two-level lumbar degenerative disease. Which appraisal best reflects the cited meta-analysis?
- At final follow-up in the meta-analysis of unilateral versus bilateral fixation for two-level lumbar degenerative disorders, which statement about functional outcome scores is supported?
- Which additional perioperative or short-term outcome set showed no significant difference between unilateral and bilateral fixation in the cited meta-analysis?
- The cited NASS evidence-based guideline concerns which condition?
- The cervical radiculopathy guideline summarized recommendations based on literature available through which date?
- Which domains were explicitly addressed by the NASS guideline on cervical radiculopathy from degenerative disorders?
- According to the guideline development approach described for degenerative cervical radiculopathy, what was used when Level I–IV evidence was absent?
