Selenium and prostate cancer: systematic review and meta-analysis
The American journal of clinical nutrition (2012) · Meta analysis · n=13254
Three high-quality studies included in the meta-analysis of toenail selenium and cancer risk indicated a reduction in prostate cancer risk (estimated RR: 0.29; 95% CI: 0.14, 0.61) with a toenail selenium concentration between 0.85 and 0.94 μg/g.
Based on RCT showing 16.77% reduction with 3mg and 26.46% reduction with 10mg monacolin K. Conservative effectiveness scaling due to limited dose-response data and variable study quality noted in meta-analyses.
