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
contextDXA densitometry is the current gold standard for the diagnosis of osteoporosis, but alternatives have been proposed. MAIN
resultREMS densitometry shows high correlation with DXA in the identification of osteoporosis, especially in the lumbar spine. RELEVANCE: REMS can be a useful tool for the identification of osteoporosis.
introductionOsteoporosis is characterized by reduced bone mineral density (BMD). The gold standard for diagnosis is bone densitometry using dual-energy X-ray absorptiometry (DXA). However, a non-ionizing technique based on quantitative ultrasound-radiofrequency echographic multispectrometry (REMS)-has recently emerged as a potential alternative.
objectiveTo evaluate the diagnostic concordance between REMS and DXA in identifying osteoporosis among postmenopausal women attending the endocrinology clinic at Hospital de San José in Bogotá, Colombia, between June and December 2024. MATERIALS AND
methodsThis descriptive cross-sectional study included 50 women with clinical indications for densitometry, for whom BMD was assessed using both DXA and REMS. Diagnostic agreement was evaluated based on the proportion of patients classified into the same diagnostic category by both methods and the corresponding concordance correlation coefficient (CCC).
resultsThe mean age of participants was 67 ± 12.4 years. According to DXA, 56% were diagnosed with osteoporosis and 38% with osteopenia. Among those diagnosed with osteoporosis by DXA, 92.9% were similarly classified by REMS. The CCC between methods was 0.53 (95% CI 0.32-0.68; p < 0.01) for the lumbar spine and 0.38 (95% CI 0.13-0.58; p < 0.01) for the femoral neck.
conclusionsREMS demonstrates substantial concordance with DXA in diagnosing osteoporosis, particularly in the lumbar spine. However, agreement varies by anatomical site, and influencing factors should be considered. This is the first study in Colombia to assess diagnostic agreement between these two techniques, and further research is recommended to validate and expand upon these findings.
