Randomized Controlled Trial Multicenter Study Comparative Study
Treatment of acute bronchitis with a liquid herbal drug preparation from Pelargonium sidoides (EPs 7630): a randomised, double-blind, placebo-controlled, multicentre study.
The objective of this study was to examine the efficacy and safety of a herbal drug preparation from the roots of Pelargonium sidoides (EPs 7630) in the treatment of acute bronchitis in adults outside the very restricted indication for an antibiotic therapy. ⋯ EPs 7630-solution is a well tolerated and effective treatment for acute bronchitis in adults outside the very restricted indication for an antibiotic therapy.

Randomized Controlled Trial Multicenter Study Comparative Study
Escitalopram versus sertraline in the treatment of major depressive disorder: a randomized clinical trial.
This trial was conducted to compare the efficacy and tolerability of a fixed dose of escitalopram 10 mg/day with sertraline optimally dosed within its recommended dose range (50-200 mg/day) for the treatment of major depressive disorder. ⋯ No differences in efficacy were observed for fixed-dose escitalopram 10 mg/day and sertraline flexibly dosed from 50-200 mg/day. At these doses, both escitalopram and sertraline were generally well tolerated.

Review Comparative Study
Potential mechanisms of stroke benefit favoring losartan in the Losartan Intervention For Endpoint reduction in hypertension (LIFE) study.
The Losartan Intervention For Endpoint reduction in hypertension (LIFE) study is the first, and, so far, the only endpoint trial in patients with hypertension and left ventricular hypertrophy (LVH) to show a divergent therapeutic outcome of one treatment modality over another with equivalent blood pressure control. The purpose of this article is to review post hoc sub-analyses of LIFE study data and other clinical studies that offer some insight into possible treatment-related differences contributing to the superior stroke outcome of losartan versus atenolol beyond blood pressure reduction. ⋯ Sub-analyses of the LIFE study data suggest that losartan's stroke benefit may arise from a mosaic of mechanisms rather than a single action. Further studies are expected to continue to delineate the mechanisms of differential responses to treatments in LIFE.

Review Comparative Study
Erythropoietic therapy for the treatment of anemia in patients with cancer: a valuable clinical and economic option.
Healthcare organizations must evaluate the cost effectiveness of the alternative therapies that are available to treat anemia and improve quality of life (QoL) of patients with cancer, that is, erythropoietic protein therapy and blood transfusion. ⋯ Significant costs are incurred when anemia in cancer is not treated. Erythropoietic protein therapy is more cost effective than blood transfusion for the treatment of cancer-related anemia. Transfusion should be reserved for patients with poor responses to erythropoietic protein or for the emergency setting, when rapid improvement in Hb is required.

Randomized Controlled Trial Multicenter Study Comparative Study
Duloxetine versus escitalopram and placebo in the treatment of patients with major depressive disorder: onset of antidepressant action, a non-inferiority study.
The goal of a non-inferiority study is to test whether a new treatment has at least as much efficacy as an established treatment. The purpose of this non-inferiority study was to compare the speed of onset of antidepressant efficacy for duloxetine (a dual serotonin and norepinephrine reuptake inhibitor) and escitalopram (a selective serotonin reuptake inhibitor). ⋯ In this study, both duloxetine and escitalopram showed significantly greater improvement on the primary efficacy measure than placebo over the 8-week acute treatment period, while no differences were observed between drugs or between drugs and placebo on response and remission rates at 8 weeks. Escitalopram at a starting dose of 10 mg QD was better tolerated than duloxetine at a starting dose of 60 mg QD. This study met its pre-defined primary objective of assessing if duloxetine was non-inferior to escitalopram in antidepressant onset efficacy, and the results show that duloxetine is at least as fast as (non-inferior to) escitalopram.
