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
introductionOsteoporosis is the principal underlying cause of fractures in postmenopausal women. Despite consensus on the importance of secondary prevention, a profound treatment gap exists, partly due to the lack of precise data on disease burden in the highest-risk population. This study aimed to determine the prevalence of osteoporosis and its associated factors specifically among postmenopausal women hospitalized for fractures, a critical evidence gap in orthopedic practice.
methodsWe conducted a multicenter cross-sectional study across eight tertiary hospitals in China between March and May 2024. Eligible participants were postmenopausal women hospitalized for fractures who met predefined inclusion and exclusion criteria. All participating surgeons completed standardized protocol training for data collection, and each study site contributed up to 160 cases.
resultsThe study included 822 postmenopausal women (mean age: 68.9 ± 10.7 years), with an overall osteoporosis prevalence of 76.9% (95% CI: 73.8%–79.7%). The prevalence was significantly higher among those with longer menopause duration (per year: adjusted odds ratio [aOR] = 1.08, 95% CI: 1.04-1.13, P < 0.001), vertebral fractures (vs patellar, tibiofibular, or ankle fractures: aOR = 3.16, 95% CI: 1.84-5.45, P < 0.001), and a history of fractures (aOR = 8.53, 95% CI: 2.56-52.94, P < 0.001).
conclusionsThis study reveals an alarmingly high prevalence (76.9%) of osteoporosis among postmenopausal women hospitalized for fractures in China, identifying prolonged menopause, vertebral fractures, and recent fracture history as key risk profiles. The findings mandate a shift in inpatient fracture care. They provide compelling evidence for implementing universal bone health assessment, specifically through in-hospital systems like Fracture Liaison Services (FLS), as a standard of care for this high-risk population to mitigate subsequent fracture risk.
