Randomized Controlled Trial Multicenter Study
Interspinous process device versus standard conventional surgical decompression for lumbar spinal stenosis: randomized controlled trial.
To assess whether interspinous process device implantation is more effective in the short term than conventional surgical decompression for patients with intermittent neurogenic claudication due to lumbar spinal stenosis. ⋯ This double blinded study could not confirm the hypothesized short term advantage of interspinous process device over conventional "simple" decompression and even showed a fairly high reoperation rate after interspinous process device implantation.

Randomized Controlled Trial Multicenter Study
Effect of behavioural-educational intervention on sleep for primiparous women and their infants in early postpartum: multisite randomised controlled trial.
To evaluate the effectiveness of a behavioural-educational sleep intervention delivered in the early postpartum in improving maternal and infant sleep. ⋯ A behavioural-educational intervention delivered in the early postpartum, in hospital, and in the first weeks at home, was ineffective in improving maternal and infant sleep or other health outcomes in the first months postpartum.

Multicenter Study Meta Analysis Comparative Study
Use of high potency statins and rates of admission for acute kidney injury: multicenter, retrospective observational analysis of administrative databases.
To quantify an association between acute kidney injury and use of high potency statins versus low potency statins. ⋯ Use of high potency statins is associated with an increased rate of diagnosis for acute kidney injury in hospital admissions compared with low potency statins. The effect seems to be strongest in the first 120 days after initiation of statin treatment.

Multicenter Study
Predictors of severe H1N1 infection in children presenting within Pediatric Emergency Research Networks (PERN): retrospective case-control study.
To identify historical and clinical findings at emergency department presentation associated with severe H1N1 outcome in children presenting with influenza-like illness. ⋯ These independent risk factors may alert clinicians to children at risk of severe outcomes when presenting with influenza-like illness during future pandemics.

Randomized Controlled Trial Multicenter Study Comparative Study
Effectiveness of PhysioDirect telephone assessment and advice services for patients with musculoskeletal problems: pragmatic randomised controlled trial.
To assess the clinical effectiveness, effect on waiting times, and patient acceptability of PhysioDirect services in patients with musculoskeletal problems, compared with usual care. ⋯ PhysioDirect is equally clinically effective compared with usual care, provides faster access to physiotherapy, and seems to be safe. However, it could be associated with slightly lower patient satisfaction.
