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: Mindfulness-Based Intervention Improves Cognitive Function in Patients With Schizophrenia in Remitted

MBI significantly improved the primary outcome of mindfulness (FFMQ) and showed promising exploratory improvements in processing speed (P300 latency) and sustained attention (CPT-IP). FER change may represent a potential indirect pathway associated with change in SQLS.

Meta-Analysis: Effects of Tai Chi combined with repetitive transcranial magnetic stimulation on sleep and emotional outcomes in older adults

The available evidence suggests that the combination of Tai Chi and rTMS may improve overall sleep severity; however, this finding should be interpreted cautiously given the small number of trials and sensitivity to individual studies. Evidence for specific sleep parameters and emotional outcomes remains inconclusive.

Randomized Controlled Trial: [The design process and protocol for a cognitive-behavioral intervention to reduce electronic cigarette use among university students]

The protocol will provide preliminary evidence on the feasibility and initial evaluation of an intervention aimed at reducing electronic cigarette use, generating information to inform the design of future studies and prevention strategies for the Mexican university student population.

Randomized Controlled Trial: Feasibility and tolerability of combining 6 Hz transcranial alternating current stimulation (tACS) at 3.2 mA and digital cognitive training in older adults with mild cognitive impairment

Higher-intensity tACS plus DCT was feasible and well tolerated in older adults with MCI. Exploratory findings suggest that active stimulation may improve inhibitory control and facilitate transfer to selected cognitive domains. Confirmation in the ongoing randomized controlled trial is warranted.

Effectiveness of Traditional Chinese Fitness Methods on Depressive Symptoms and Glycaemic Control in Patients With Type 2 Diabetes and Comorbid Depression

This review provides preliminary evidence that TCFMs may confer benefits on mental health and glycaemic regulation in patients with T2DM and comorbid depression. However, given the low certainty of the evidence, high heterogeneity, and methodological limitations, these findings should be interpreted cautiously.

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.
