Towards efficient osteoporosis screening: a simple and practical approach using OSTA and FRAX risk factors.

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 a major public health concern, particularly in the aging population, where fragility fractures significantly impact quality of life and mortality. Despite the importance of early detection, screening rates for osteoporosis in Japan remain low. The Osteoporosis Self-Assessment Tool for Asians (OSTA) and Fracture Risk Assessment Tool (FRAX) are noninvasive screening tools. This study aimed to develop an efficient method for screening osteopenia using these tools. MATERIALS AND
methodsWe analyzed data from 1060 Japanese women aged 40-74 years from the Research on Osteoarthritis/Osteoporosis Against Disability (ROAD) study. The OSTA and FRAX scores, as well as individual FRAX risk factors, were assessed for their ability to detect osteopenia. As FRAX score calculations are not publicly available, we evaluated the discriminative ability of the seven risk factors individually. Prior fragility fractures were deemed the most critical, and all 64 possible combinations of the remaining six risk factors were analyzed.
resultsOSTA had the highest discriminative ability (AUC = 0.81), followed by FRAX-Hip (AUC = 0.79) and FRAX-Major (AUC = 0.77). The sensitivity and specificity of OSTA ≤ -1 were 83.7% and 62.6%, respectively. The most effective criterion was OSTA ≤ -1 or at least one FRAX risk factor, achieving a sensitivity of 90.4%, specificity of 47.2%, and positive predictive value of 63.3%.
conclusionA simple, noninvasive osteopenia screening method combining OSTA ≤ -1 and FRAX risk factors identified at-risk individuals effectively. This approach could enhance osteoporosis screening in Japan and facilitate early intervention and fracture prevention.
