Effects of Daily Zinc Alone or in Combination with Other Nutrient Supplements on the Risk of Malaria Parasitaemia: A Systematic Review and Meta-Analysis of Randomised Controlled Trials
Nutrients (2023) · Meta analysis · n=1339
The effect sizes, represented as risk ratios (RRs) with 95% confidence intervals (CIs), were standardised by transforming them into log RRs and then pooling them using a fixed-effects or random-effects model depending on the heterogeneity across studies.
Prevalence of Zinc Deficiency in Inflammatory Bowel Disease: A Systematic Review and Meta-Analysis
Nutrients (2022) · Meta analysis · n=806
Pooled analyses by the IBD subgroup showed a total population of 1677 with CD, for an overall mean zinc deficiency prevalence of 54% and 95% confidence intervals (CI) ranging from 0.51 to 0.56, versus 41% (95%CI 0.38-0.45) in the UC population (n = 806).
Based on 3 RCTs (n=88, n=66, n=20) showing improvements in muscle endurance and strength. Effects observed primarily in middle-aged and older adults over 8-16 weeks. Studies used synthetic urolithin A forms with high bioavailability.
Based on meta-analyses showing reduced respiratory tract infections and improved immune markers (CD3/CD4). Effects primarily in deficient individuals. Take with food to reduce nausea risk.
