★ Breakthrough Medical Research • 15 Landmark Multi-Trial Guides • 6,280 Indexed Studies

Randomized Controlled Human Trials (RCTs) (1,760 Indexed Studies)

Prospective randomized human trials, crossover pharmacokinetic studies, and ClinicalTrials.gov interventional readouts with direct participant sample sizes (N). Every study summary reports the trial design, participant sample size (N), primary outcome highlight, and direct link to the formal NCBI PubMed or federal record.

★ #1 Lead Breakthrough Study • NEJM SURMOUNT-1 (176 Weeks) N = 1,032 Adults • p < 0.001

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).

Randomized Controlled Trial: Effects of intradermal lymphocyte therapy in patients with recurrent pregnancy loss: secondary analysis of a randomized controlled trial investigating purinergic signaling, inflammation, and cellular energy status (N = 100)

Low-dose ILT may be associated with improved successful pregnancy and live birth rates in RPL patients. These clinical outcomes coincided with changes in purinergic signaling, inflammatory cytokines, and cellular energy status; however, formal mediation cannot be inferred from the present analysis.

Randomized Controlled Trial: Effectiveness of a Structured Post-Platelet Rich Plasma Rehabilitation Approach on Pain and Function in Subacromial Pain Syndrome

Corbin Posture Scale scores decreased in both groups (p < 0.05). Pain reduction was greater in the study group (VAS: from 9.00 ± 0.67 to 2.92 ± 1.14 versus from 9.11 ± 0.64 to 7.96 ± 0.75; SF-MPQ: from 27.07 ± 4.41 to 10.07 ± 3.33 versus from 21.33 ± 2.46 to 19.37 ± 2.35; p < 0.001).

Randomized Controlled Trial: Exploratory serum renal biomarker and eGFR responses to high-protein diets during resistance versus concurrent training in resistance-trained men

In resistance-trained men, 16 weeks of high protein intake did not produce statistically detectable differences in renal biomarker or eGFR changes compared with moderate protein intake, irrespective of training modality.

Randomized Controlled Trial: Cost-effectiveness of onabotulinumtoxinA versus topiramate in chronic migraine in the US: an economic analysis of the FORWARD randomized trial

OnabotA was a cost-effective preventive treatment of chronic migraine versus topiramate. Although OnabotA had higher drug acquisition costs, these were offset by reduced HCRU costs due to fewer migraines, resulting in a low incremental cost per headache-day avoided versus topiramate.

Randomized Controlled Trial: Efficacy of a Gamified Training Program for Improving Occupational Health and Safety Knowledge Among Italian Secondary School Students

These findings support the integration of gamified OHS training into secondary school curricula to strengthen early safety education in line with the principles of Legislative Decree 81/2008. Future studies should include larger samples, address item-level weaknesses and explore long-term behavioural outcomes.

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.
