This Cochrane systematic review analyzed 49 randomized controlled trials to assess the impact of combination hormonal contraceptives (CHCs) on weight. The findings indicate no substantial evidence linking CHC use to significant weight gain. Trials comparing CHCs to placebo or no intervention showed minimal weight changes, and discontinuation rates due to
This systematic review and meta-analysis evaluated eight randomized controlled trials involving 1,022 overweight or obese adults (BMI ≥25) to compare the effectiveness of combined behavioral weight management programs (BWMPs) incorporating both diet and physical activity versus diet-only or physical activity-only interventions. Short-term (3–6 months) weight loss was similar between combined
This 2011 systematic review and meta-analysis evaluated the efficacy of isolated aerobic exercise programs in overweight and obese populations. Analyzing 14 randomized controlled trials encompassing 1,847 participants, the study found that moderate-intensity aerobic exercise over 6 to 12 months led to modest reductions in weight (approximately 1.6–1.7 kg) and waist
This 2015 meta-analysis evaluated 15 randomized controlled trials involving 17,186 overweight or obese adults (mean age 52 years, 53% female) to assess the impact of intentional weight loss on all-cause mortality. Participants underwent lifestyle-based weight loss interventions over periods ranging from 18 months to 12.6 years, achieving an average weight
This 2004 review by Astrup et al. evaluates the efficacy and safety of low-carbohydrate diets, such as the Atkins diet, in weight loss. The authors discuss randomized controlled trials comparing low-carbohydrate diets to low-fat diets, noting that while low-carbohydrate diets may lead to greater weight loss at six months, differences
This 2023 comprehensive review evaluates randomized clinical trials investigating methylene blue (MB) and its derivatives for Alzheimer’s disease (AD) treatment. MB, a thiophenazine dye with FDA approval for various conditions, can cross the blood-brain barrier, making it a candidate for central nervous system therapies. The review highlights MB’s potential benefits,
This systematic review and meta-analysis evaluated the efficacy and safety of intravenous (IV) iron therapy in reducing the need for allogeneic red blood cell transfusions. The analysis included 72 randomized controlled trials encompassing 10,605 patients. Findings demonstrated that IV iron therapy significantly increased hemoglobin levels (standardized mean difference of 6.5
This 2022 systematic review and network meta-analysis evaluated 13 randomized controlled trials involving 944 patients to assess the efficacy of a low FODMAP diet in managing irritable bowel syndrome (IBS). The analysis revealed that the low FODMAP diet ranked highest in improving global IBS symptoms, abdominal pain, bloating, and bowel
This 2018 systematic review and meta-analysis evaluated the efficacy and risks of PSA-based prostate cancer screening across five randomized controlled trials involving over 721,000 men. The findings indicate that PSA screening may lead to a small reduction in prostate cancer-specific mortality over 10 years (incidence rate ratio [IRR] 0.96; 95%
This 2015 meta-analysis reviewed data from three randomized controlled trials involving 294 patients to assess topiramate’s efficacy and safety in treating essential tremor (ET). The analysis showed that topiramate significantly improved tremor severity, motor function, and reduced functional disability compared to placebo. The mean difference in the Fahn–Tolosa–Marin Tremor Rating
