Midlife physical activity, BMI, and hip fracture risk five decades later in men: a NOREPOS study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Research on hip fracture prevention in men is limited. In men, physical activity and body mass index were independently and jointly associated with hip fracture risk, with the highest risk among inactive and thin men. Promoting exercise and healthy weight in midlife may reduce fracture burden and support healthy ageing. PURPOSE: Hip fractures predominantly affect older people with frailty. The incidence increases with age, and the number is expected to increase substantially due to population aging. Physical inactivity and low body mass index (BMI) are key modifiable risk factors for hip fractures. This study aimed to explore the associations of physical activity and BMI with long-term hip fracture risk in men.
methodThis prospective cohort study included 12,900 men aged 40-49 years from the Oslo study 1972-1973. A questionnaire assessed physical activity, whereas height and weight were measured. Hip fractures were identified through linkage to a national database. Cox regression calculated adjusted hazard ratios (HR) with 95% confidence intervals (CI) for hip fracture according to physical activity level. A secondary analysis examined a composite variable combining activity level (inactive/active) and BMI (< 22/22-24.9/ ≥ 25 kg/m
resultsDuring 195,384 person-years of follow-up, 1542 men (12%) sustained a hip fracture at a median age of 82 years. Inactive men had a 38% higher risk (HR 1.38 [95% CI 1.16-1.63]) than active men. Active men had a lower hip fracture risk across all categories of BMI, while the greatest risk was found in inactive men with a BMI < 22 kg/m
conclusionsPhysical inactivity and low BMI in midlife were independently associated with increased long-term hip fracture risk. Inactive and thin men had the greatest risk, suggesting that maintaining physical activity in mid-life is important for healthy ageing and independence.
