Neither evening primrose oil nor fish oil offered clear benefit over control oils in the treatment of mastalgia.
In the long term, both treatments showed no benefit over control.
Two randomized phase 3 trials of ipilimumab in advanced melanoma have reported overall survival benefit over control arms, with a side-effect profile that was managed with proactive treatment guidelines as outlined in the individual protocols 22– 22.
Concerning nonpharmacologic interventions, Bernardy et al. [ 14] performed a meta-analysis of 23 studies that indicated that treatment with CBTs provided a small incremental benefit over control interventions in reducing pain, negative mood, and disability at end of treatment and at long-term follow-up (median, 6 months) in patients with FM.
None of six trials of traditional Chinese medicinal herbs, three using a combination of medicines, showed a significant benefit over controls for menopausal symptoms.
After administering several different doses of the drug to 166 patients who had been diagnosed with early stage Alzheimer's, the company reported that 27 people who had received the highest dose of 10 mg per kilogram showed significant cognitive benefits over controls, as well as reduced levels of protein.
Despite the non cariogenicity of xylitol, we are unable to advocate its use as a caries prevention measure since it did not provide any measurable benefit over a control group that received oral hygiene instructions, regular cleanings, and topical fluoride application.
Their design, which controls the type I error rate and power for each pairwise comparison, discontinues randomisation to poorly performing arms at interim analyses if they fail to show a pre-specified level of benefit over the control arm.
Within this trial, patients with QRS width of 120 130 ms had a significant benefit over the control group, compared to the non-significant change in patients with QRS <120 ms; strengthening the argument of using QRS for better predicting the response of CRT, an electrical intervention.
These results suggest that beneficial effects of LS administration on biomarkers of oxidative stress, inflammation, tissue injury, and apoptosis were further strengthened by the favorable outcome in the study group, that is, LS-treated CLP animals had about 22% survival benefit over CLP controls.
Quality scores are R = randomised, DB = double-blinding, W = Withdrawals (Jadad et al, 1996) Note: Details of patient groups are given in the textNumbers-needed-to-treat are only given where there is a statistical benefit of treatment over control.
