NICEVIVA GRADE Evidence Methodology & 14,357-Study PubMed Audit
“Backed by a study” often means a petri-dish or rodent experiment. NICEVIVA separates human randomized controlled trials (RCTs) and meta-analyses from preclinical hype using standardized GRADE methodology.
Cherry-Picked Single Trials vs. Pooled Meta-Analytic Effect Sizes (95% CI)
An underpowered 15-person pilot study cannot establish clinical efficacy. Each NICEVIVA monograph reports the exact count of Meta-Analyses, Systematic Reviews, and RCTs alongside pooled participant counts (n) and quantitative effect sizes.
Step-by-Step Evaluation & Dosing Protocol
NCBI PubMed Ingestion & Retraction Gate
Ingests indexed human studies from NCBI PubMed while automatically blocking retracted publications.
Study Design Classification & Quantitative Extraction
Extracts participant sample sizes, standardized mean differences (SMD), odds/risk ratios, 95% confidence intervals, and p-values.
GRADE Tiering & Balanced Worth/Skip Verdict
Presents a balanced two-column clinical verdict: cohorts with proven benefit versus cohorts who should skip or exercise caution.

1. How to Interpret GRADE Evidence Levels
High and Moderate GRADE ratings indicate consistent findings across multiple well-powered RCTs and meta-analyses, whereas Low ratings signal preliminary or heterogeneous evidence.
Hierarchy of Clinical Evidence in NICEVIVA Monographs
| Study Design | Hierarchy Tier | Key Metrics Audited | Interpretation Caveat |
|---|---|---|---|
| Meta-Analysis & Systematic Review | Tier 1 (Highest) | Pooled effect size, 95% CI, heterogeneity (I²) | Check quality of underlying trials |
| Randomized Controlled Trial (RCT) | Tier 2 (High) | Sample size (n), placebo-adjusted p-value | Verify exact salt form and trial duration |
| Observational Cohort | Tier 3 (Moderate/Low) | Hazard/Odds ratios, confounder adjustment | Demonstrates association, not causation |
| Preclinical (In Vitro / Animal) | Mechanistic Only | Biochemical pathway exploration | Cannot be extrapolated directly to human dosing |
