How this library is organized

Studies default to publication date, newest first, not the date a summary was added. Choose Most relevant for human-first editorial reading order, not an effectiveness or quality ranking. Design, topic and intervention-candidate labels assist discovery; they are not formal appraisals. Result-direction and sample-size filters only use existing verified metadata; missing values are excluded when those filters are active. Study counts are publications, not unique trials or participants.

Cardiovascular effects of continued vs. discontinued anabolic-androgenic steroid use: a longitudinal follow-up study.

A longitudinal cohort examined cardiac changes after continued or discontinued steroid use.

Population, studied exposure & key finding
Population
70 men with steroid-use histories and 35 nonusing weightlifters returned for follow-up.
Studied dose & duration
Self-selected steroid use, cessation or continued abstinence; no standardized treatment regimen.

Population, studied exposure & key finding
Population
410 randomized participants; 393 in the primary analysis.
Studied dose & duration
Oral nicotinamide riboside 500 mg twice daily versus placebo for 52 weeks, alongside stable dopaminergic treatment.
Finding
The primary symptom score favored placebo: adjusted difference 2.72 points (95% CI 0.47–4.98), indicating greater worsening with NR. Four key secondary outcomes were null. Serious adverse events: 8.3% versus 14.1%.

Betaine supplementation modulates mitochondrial and redox-related adaptations in premenopausal women with overweight: a randomized controlled trial.

A randomized trial examined blood-cell mitochondrial and antioxidant markers.

Population, studied exposure & key finding
Population
Premenopausal women with overweight or obesity; sample size not specified in the abstract.
Studied dose & duration
Anhydrous betaine 3 g/day versus placebo for eight weeks.
Finding
Citrate-synthase protein concentration changed by 102.3 μg/mg protein more than placebo (95% CI 3.19–201.4), despite nonsignificant within-group changes. Catalase activity increased; other measured mitochondrial/redox markers did not clearly improve.

UBT251, a novel triple GLP-1, GIP, and glucagon receptor agonist, in adults with overweight or obesity: A multicenter, randomized phase 2 trial.

A phase 2 trial tested a triple-receptor agonist for weight reduction.

Population, studied exposure & key finding
Population
205 adults with overweight/obesity and no diabetes.
Studied dose & duration
Weekly subcutaneous UBT251 targets of 2, 4 or 6 mg versus placebo for 24 weeks; two starting schedules for the 4 mg target. Route confirmed in the registry.
Finding
Weight changed -19.7% to -13.6% across active groups, versus -2.0% with placebo. Gastrointestinal events were most frequent, generally mild or moderate.

Population
15 participants with metabolic dysfunction-associated steatotic liver disease.
Studied dose & duration
Oral PF-06835919 300 mg daily versus placebo for six weeks per treatment period; route and dose verified in the trial registry.
