# Translate clinical trial methods, statistical endpoints, and PubMed studies into plain language.

Highlight hazard ratios, confidence intervals, inclusion criteria, or biochemical pathways on PubMed, NEJM, and medical textbooks to get clear, contextual explanations on screen.

> **Best fit:** Best for medical students, clinicians, researchers, and informed patients reading peer-reviewed clinical studies and biomedical literature.

## Live Webpage Walkthrough

- **Source:** PubMed Central — Phase 3 Randomized Clinical Trial (Results) (`pmc.ncbi.nlm.nih.gov/articles/PMC109482/`)
- **Recommended Context Mode:** Detailed

**Highlighted Passage:**
> The primary composite endpoint occurred in 142 patients (8.4%) in the intervention group and 198 patients (11.7%) in the placebo group (hazard ratio, 0.71; 95% confidence interval [CI], 0.57 to 0.88; P=0.002).

**User Question (Shortcut):** "Explain the difference between the relative risk reduction and absolute risk reduction here, and calculate the NNT."

**Vezz me On-Screen Answer:**
1. Relative Risk Reduction (RRR): A hazard ratio of `0.71` means a ~29% relative reduction in the rate of the primary endpoint (`1 - 0.71`), with the 95% CI wholly below 1.0 (`0.57` to `0.88`), making it statistically significant (`P=0.002`).
2. Absolute Risk Reduction (ARR): `11.7% - 8.4% = 3.3%` absolute reduction over the study period.
3. Number Needed to Treat (NNT): `1 / 0.033 ≈ 31`. Roughly 31 patients need to be treated with the intervention over the trial duration to prevent 1 primary composite event.

**Suggested Follow-Ups:**
- "Why is a composite endpoint used here, and how could that skew clinical interpretation?"
- "What does the width of the 95% confidence interval (`0.57 to 0.88`) tell us about precision?"
- "Summarize this finding in plain language for a study flashcard."

## Step-by-step workflow

1. **Highlight the statistical endpoint or mechanism**: Select the exact paragraph reporting hazard ratios, odds ratios, p-values, or physiological mechanisms.
2. **Press Ctrl+Shift+X on the study page**: Vezz me uses the study title and section headings to keep abbreviations and cohort details accurate.
3. **Check clinical vs statistical significance**: Ask follow-ups about absolute vs relative effect sizes, sample size power, and potential confounders.

## Decode biomedical acronyms and pathways without losing your place

Immunology, pharmacology, and oncology papers often pack 10+ signaling acronyms into a single sentence.

- Highlight a dense pathway paragraph and ask for a step-by-step causal chain (`A activates B -> inhibits C`)
- Keep the paper's figures visible right next to the Vezz me explanation panel
- Switch between a technical Medical Student prompt and a Plain-English Patient Education prompt

## Critique study design in seconds

Use Vezz me to evaluate the strength of evidence while reading the Methods and Limitations sections.

- Check intention-to-treat vs per-protocol analysis differences
- Identify surrogate endpoints vs hard clinical outcomes
- Always verify clinical decisions against official guidelines and primary medical judgment
