Once-Weekly Tirzepatide Cuts Type 2 Diabetes Progression by 94% Over 3 Years—With a 22.9% Sustained Weight Reduction

The Plain-English Receipt: Only 1.2% of prediabetic adults on Tirzepatide progressed to Type 2 diabetes over 3.4 years vs. 19.3% on placebo (Absolute Risk Reduction = 18.1% • Number Needed to Treat = 6).

Phase III Randomized Trial: Targeting Accelerated Aging in COPD: The AMICO (A Trial of Metformin In COpd) Trial Design (N = 212)

AMICO is the first randomized trial specifically designed to evaluate metformin as a gerotherapeutic and disease-modifying intervention in COPD. The study may provide novel evidence supporting geroscience-based approaches to slow disease progression and improve long-term outcomes in patients with COPD.

Randomized Controlled Trial: A randomized comparison of comprehensive weight loss intervention vs. usual care on recurrences of atrial fibrillation in obese patients after catheter ablation: HOBIT-AF trial (N = 167)

HOBIT-AF trial showed that despite the beneficial effect of body weight reduction on metabolic profile of obese patients with predominantly paroxysmal AF after CA, no reduction in AF/AT recurrence was observed in comparison with control patients. This may be likely due to low AF burden after previous CA, limiting further improvement.

Frequently Asked Questions About dotMD Clinical Trial Breakdowns

Why does dotMD report both Absolute Risk Reduction (ARR) and Relative Risk Reduction (RRR) on clinical trials?

Traditional health headlines often exaggerate findings by reporting only Relative Risk Reduction—for example, claiming a drug cuts risk by 50% when the event rate dropped from 2% to 1% (an Absolute Risk Reduction of just 1.0 percentage point, meaning 100 patients must take the drug for 1 person to benefit, or NNT = 100). On dotMD, every flagship study breakdown reports both Relative Risk and Absolute Risk alongside the exact sample size (N) and trial duration.

How does dotMD separate human randomized controlled trials (RCTs) from animal or observational studies?

Every study on dotMD displays its exact Study Design Tier at the top of the card (Phase 3 Randomized Trial, Randomized Controlled Trial, Meta-Analysis & Systematic Review, Multi-Trial Clinical Evidence Synthesis, Journal Watch Cohort, or FDA Safety Alert) along with the human participant count (N). Preclinical mouse or cell-culture data is never presented as human clinical proof.

Why did dotMD replace synthetic "Study Rigor Scores" with primary PubMed PMIDs and trial metadata?

Arbitrary 0-to-100 rigor scores obscure what actually makes a study trustworthy. Instead of synthetic scores, dotMD surfaces the verifiable primary evidence signals: exact NCBI PubMed IDs (PMID), ClinicalTrials.gov registration numbers (NCT), double-blind vs. crossover design, sample size (N), p-values / Hazard Ratios, and study limitations.

How do dotMD Research Breakdowns connect to Conditions, Medications, Supplements, and Specialist Doctors?

Medical research is only useful if you can act on it safely with your clinician. Every flagship research synthesis links directly to the parent Condition diagnostic cutoff guide, the Medication FDA DailyMed & CMS NADAC wholesale price ledger, the Supplement elemental weight decoder, and our High-CPT-Volume Specialist Directory.
