# Med-Read.org — Independent Open-Access Medical Literature Appraisal & Archival Monograph Desk

> An independent, non-commercial clinical epidemiology and study-appraisal reference helping patients, clinicians, and researchers decode relative vs. absolute risk (ARR), Number Needed to Treat (NNT), surrogate vs. hard clinical endpoints, open-access journal peer-review integrity, and environmental noise epidemiology.
> Historical Provenance: From 2019 to 2022, `med-read.org` hosted MedRead Publishing Group open-access medical monographs cited by the World Health Organization Eastern Mediterranean Regional Office (`emro.who.int`), Heriot-Watt University (`researchportal.hw.ac.uk`), Scientific Research Publishing (`scirp.org`), and Auctores (`auctoresonline.org`). Maintained in English (`/`), Spanish (`/es/`), and Simplified Chinese (`/zh/`).

## Core Methodological & Clinical Reference Findings

- **How to Read a Medical Paper in 10 Minutes (`/study-appraisal`)**: Translates Relative Risk Reduction (`RRR = (CER - EER) / CER`) into Absolute Risk Reduction (`ARR = CER - EER`) and Number Needed to Treat (`NNT = 1 / ARR`). Demonstrates why a 50% relative risk drop from 0.2% to 0.1% yields an ARR of 0.1% (NNT = 1,000), and audits p-hacking, immortal time bias, and underpowered subgroup claims under CONSORT 2025 and GRADE rules.
- **Open-Access Integrity & Peer-Review Verification (`/open-access-integrity`)**: Explains the critical distinction between PubMed Central (`PMC` full-text repository) and `MEDLINE` (NLM Literature Selection Technical Review Committee curation), and gives a 5-step verification protocol across Crossref DOI metadata, DOAJ indexing, ClinicalTrials.gov (`NCT`) pre-registration, and Retraction Watch.
- **Environmental Noise Exposure & Cardiovascular Epidemiology (`/environmental-noise-health`)**: Preserves the historical 2020 MedRead monograph on peri-urbanization and acoustic noise exposure (`#scientific-9-946` / `Zia MA et al.`) cited by Heriot-Watt University and SCIRP, and synthesizes the WHO Environmental Noise Guidelines (road traffic limits of `53 dB Lden` and `45 dB Lnight`, where each `+10 dB Lden` above 53 dB increases ischemic heart disease incidence by `RR 1.08`, 95% CI 1.01-1.15).
- **Cardiometabolic Trial Ledger (`/cardometabolic-evidence`)**: Contrasts laboratory surrogate markers (`LDL-C`, `HbA1c`) against hard MACE and all-cause mortality endpoints across primary/secondary statin trials (`NNT 83-100` vs `NNT 28-39` over 5 years), SGLT2 inhibitors (`DAPA-HF`, `EMPA-REG`), and GLP-1 receptor agonists (`SELECT` semaglutide `ARR 1.5%`, `NNT 67` over 39.8 months).
- **Oncology Trial Endpoints Decoded (`/oncology-endpoints`)**: Decodes Overall Survival (`OS`) vs. Progression-Free Survival (`PFS`), Objective Response Rate (`ORR`), and Pathologic Complete Response (`pCR`), illustrating why over 60% of oncology surrogate approvals lack subsequent OS confirmation while carrying CTCAE Grade 3/4 toxicity.
- **Infectious Disease & Diagnostic Epidemiology (`/infectious-epidemiology`)**: Applies Bayes' theorem to diagnostic sensitivity/specificity in low-prevalence cohorts (showing why a 98% specific test at 0.5% prevalence yields only a `19.7%` Positive Predictive Value) and contrasts RCT vaccine efficacy against observational real-world effectiveness.
- **Global Clinical Trial Hubs & Diagnostic Coordinate System (`/global-clinical-research`)**: Benchmarks clinical trial registry volume (WHO ICTRP / ClinicalTrials.gov), ethics approval timelines, and public academic diagnostic workup costs (3.0T MRI, PET-CT, NGS genomic panels) across the US (`NIH/FDA`), EU (`EMA`), UK (`NHS/NIHR`), Japan (`PMDA`), and China (`NMPA` / National Medical Centers).
- **2019-2022 Archival Monograph Concordance (`/archived-articles`)**: Complete citation index preserving the 26 historical MedRead journal scopes and legacy article anchors (`#who-emro-pediatrics`, `#scientific-9-946`, `#gfm-1001-polypharmacy`, `#article-pdf-9`).
