Outcome guide · four released stories
Strength, bones and independence
Did the study measure density, fractures, falls or function?
Keep bone density, fractures, falls, mobility disability and physical-function tests in their own lanes.
Follow the governed path
Ask what was measured before comparing the headline.
Every field below is projected from the released path, Evidence at a glance and published-coverage records. The “why this follows” note explains reading order only; it is not an evidence-strength, efficacy, importance or popularity judgment.
Why this follows in the reading path: Start by seeing why a bone-density change cannot substitute for the clinical fracture outcome.
- Intervention or exposure
- testosterone
- Population or model
- 5,204 TRAVERSE participants: middle-aged and older men with symptoms, repeatedly low testosterone and preexisting or high cardiovascular risk
- Study design and comparator
- randomized trials
- Measured outcome
- clinical fractures and bone-density measures
- Released bottom line
- Clinical fractures were more frequent with testosterone than placebo in TRAVERSE; a smaller substudy’s bone-density gain cannot substitute for fracture outcomes.
- What this evidence did not establish
- Testosterone did not prevent fractures in TRAVERSE
- Evidence scope
- Human fracture and bone-density outcomes · randomized trials

Read the released storyWhy this follows in the reading path: Compare an osteoporosis trial that measured vertebral and hip fractures directly while retaining population and safety limits.
- Intervention or exposure
- zoledronic acid
- Population or model
- 7,765 postmenopausal women with osteoporosis; mean age about 73
- Study design and comparator
- large randomized trial
- Measured outcome
- vertebral, hip and nonvertebral fractures plus bone density
- Released bottom line
- HORIZON reduced vertebral and hip fractures in postmenopausal osteoporosis, with outcome-specific duration and safety limits—not evidence of slower aging.
- What this evidence did not establish
- Zoledronic acid reduced fractures in osteoporosis—not aging itself
- Evidence scope
- Human fracture outcomes · large randomized trial

Read the released storyWhy this follows in the reading path: Move from bone outcomes to a concrete mobility-disability result in vulnerable older adults.
- Intervention or exposure
- exercise
- Population or model
- Community-dwelling and hospitalized older adults, including mobility-limited participants
- Study design and comparator
- randomized trials
- Measured outcome
- mobility disability and discharge function
- Released bottom line
- LIFE supports a meaningful mobility outcome in vulnerable older adults, while lifespan and universal-program claims remain untested.
- What this evidence did not establish
- Structured physical activity reduced late-life mobility disability—not aging itself
- Evidence scope
- Human function · randomized trials

Read the released storyWhy this follows in the reading path: Finish with a walking-test result where subgroup and secondary analyses do not establish broader independence or longevity.
- Intervention or exposure
- testosterone
- Population or model
- 790 symptomatic men age 65 or older with repeatedly low testosterone; 390 enrolled in the Physical Function Trial
- Study design and comparator
- one-year randomized trials
- Measured outcome
- six-minute walking distance and a 50-meter improvement threshold
- Released bottom line
- The prespecified Physical Function Trial threshold was not significant in its enrolled subgroup; broader secondary walking results do not establish disability prevention, healthspan or longevity.
- What this evidence did not establish
- Testosterone’s walking result was modest—not an anti-aging effect
- Evidence scope
- Human physical-function outcomes · one-year randomized trials
