Review Comparative Study
Comparative assessment of implantable hip devices with different bearing surfaces: systematic appraisal of evidence.
To determine comparative safety and effectiveness of combinations of bearing surfaces of hip implants. ⋯ There is limited evidence regarding comparative effectiveness of various hip implant bearings. Results do not indicate any advantage for metal on metal or ceramic on ceramic implants compared with traditional metal on polyethylene or ceramic on polyethylene bearings.

Randomized Controlled Trial Comparative Study
Overnight closed loop insulin delivery (artificial pancreas) in adults with type 1 diabetes: crossover randomised controlled studies.
To compare the safety and efficacy of overnight closed loop delivery of insulin (artificial pancreas) with conventional insulin pump therapy in adults with type 1 diabetes. ⋯ These two small crossover trials suggest that closed loop delivery of insulin may improve overnight control of glucose levels and reduce the risk of nocturnal hypoglycaemia in adults with type 1 diabetes. Trial registration ClinicalTrials.gov NCT00910767 and NCT00944619.

Randomized Controlled Trial
Functional outcomes of multi-condition collaborative care and successful ageing: results of randomised trial.
To evaluate the effectiveness of integrated care for chronic physical diseases and depression in reducing disability and improving quality of life. ⋯ Integrated care that covers chronic physical disease and comorbid depression can reduce social role disability and enhance global quality of life. Trial registration Clinical Trials NCT00468676.

Randomized Controlled Trial
Effect of using reporting guidelines during peer review on quality of final manuscripts submitted to a biomedical journal: masked randomised trial.
To investigate the effect of an additional review based on reporting guidelines such as STROBE and CONSORT on quality of manuscripts. ⋯ Additional reviews based on reporting guidelines improve manuscript quality, although the observed effect was smaller than hypothesised and not definitively demonstrated. Authors adhere more to suggestions from conventional reviews than to those from additional reviews, showing difficulties in adhering to high methodological standards at the latest research phases. To boost paper quality and impact, authors should be aware of future requirements of reporting guidelines at the very beginning of their study. Trial registration and protocol Although registries do not include trials of peer review, the protocol design was submitted to sponsored research projects (Instituto de Salud Carlos III, PI081903).
