Multicenter Study Comparative Study
Real-world utilization of DMARDs and biologics in rheumatoid arthritis: the RADIUS (Rheumatoid Arthritis Disease-Modifying Anti-Rheumatic Drug Intervention and Utilization Study) study.
Rheumatoid Arthritis (RA) Disease-Modifying Anti-Rheumatic Drug (DMARD) Intervention and Utilization Study (RADIUS) is a unique, real-world, prospective, 5-year, observational study of over 10 000 patients with RA. RADIUS provides a snapshot of use patterns, effectiveness, and safety of DMARDs, biologics, and combination therapies used to manage RA in clinical practice. ⋯ These real-world data provide evidence of the prescribing practices of rheumatologists in 2001-2003. Future analyses will allow evidence-based comparisons of the long-term safety and effectiveness of DMARDs, biologics, and combination therapies to assist physicians in clinical decision-making.

Randomized Controlled Trial Multicenter Study
Efficacy of etoricoxib 60 mg/day and diclofenac 150 mg/day in reduction of pain and disability in patients with chronic low back pain: results of a 4-week, multinational, randomized, double-blind study.
The efficacy and safety of etoricoxib 60 mg/day in patients with established chronic low back pain (CLBP) were compared with those of diclofenac 150 mg/day in a 4-week, multicentre, randomized, double-blind, parallel-group trial. Four hundred and forty-six adult patients with CLBP (Quebec Task Force on Spinal Disorders Class 1 or 2) and with worsening pain upon discontinuation of pre-study analgesic medication were enrolled in the study. The study primary efficacy endpoint was change from baseline in Low Back Pain Intensity Scale (LBP-IS) score over the 4-week treatment period. Secondary and other efficacy endpoints included: changes in Roland and Morris Disability Questionnaire (RMDQ), Patient Global Assessment of Response to Therapy (PGART) and Low Back Pain Bothersomeness Scale (LBP-BS) scores. Early efficacy was assessed using PGART and LBP-IS scores 4 h after the first dose on the mornings of Days 1, 2 and 3. The overall safety and tolerability of etoricoxib 60 mg/day during 4 weeks of treatment were also assessed. ⋯ The results of this study confirm that, for adult patients with CLBP, etoricoxib 60 mg once daily over 4 weeks is effective for relief of pain and improvement of physical function and comparable to high-dose diclofenac 150 mg daily.

Randomized Controlled Trial Multicenter Study Clinical Trial
Low-dose cyclobenzaprine versus combination therapy with ibuprofen for acute neck or back pain with muscle spasm: a randomized trial.
This prospective, randomized, open-label, multicenter, community-based study was conducted to compare cyclobenzaprine 5 mg three times daily (TID) orally (CYC5) given for 7 days as monotherapy or in combination with ibuprofen 400 mg TID (CYC5/IBU400) or 800 mg TID (CYC5/IBU800) in adults with acute neck or back pain with muscle spasm. ⋯ This randomized, community-based clinical trial demonstrated that combination therapy with cyclobenzaprine 5 mg TID plus ibuprofen was not superior to cyclobenzaprine 5 mg TID alone in adult patients with acute neck and back pain with muscle spasm. All treatments were well tolerated.

Randomized Controlled Trial Multicenter Study Comparative Study
Second-degree burns: a comparative, multicenter, randomized trial of hyaluronic acid plus silver sulfadiazine vs. silver sulfadiazine alone.
This multicenter, multinational, randomized, double-blind, controlled, parallel-group study, was designed to assess the efficacy and safety of a fixed combination topical medicinal product, containing 0.2% hyaluronic acid and 1% silver sulfadiazine (HA-SSD) (Connettivina Plus cream) versus 1% silver sulfadiazine cream alone (SSD), in the treatment of second-degree burns. ⋯ The observed shorter time to healing caused by the fixed combination is clinically relevant and further demonstrates the wound healing activity of HA.

Randomized Controlled Trial Multicenter Study
Rivastigmine and donepezil treatment in moderate to moderately-severe Alzheimer's disease over a 2-year period.
Randomised controlled trials that directly compare cholinesterase inhibitors for the treatment of Alzheimer's disease have been characterised by significant methodological limitations. As a consequence, they have failed to establish whether there are differences between agents in this class. To help address this question, a double-blind, randomised, controlled, multicentre trial was designed to evaluate the efficacy and tolerability of cholinesterase inhibitor treatment in patients with moderate to moderately-severe Alzheimer's disease over a 2-year period. ⋯ Cholinesterase inhibitor treatment may offer continued therapeutic benefit for up to 2 years in patients with moderate AD. Although both drugs performed similarly on cognition and behaviour, rivastigmine may provide greater benefit in activities of daily living and global functioning.
