Canal Bone Ratio for Predicting Bone Mineral Density in Lumbar Degenerative Diseases.

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
backgroundDespite its clinical importance, osteoporosis remains underdiagnosed, particularly in spinal surgery patients, where bone quality affects surgical outcomes. Existing screening methods are often costly or inaccessible, highlighting the need for a simpler alternative.
objectiveThe purpose of the present study was to assess the canal bone ratio (CBR) as a predictive tool for bone mineral density (BMD) in patients with lumbar degenerative diseases and establish a specific cutoff value for diagnosing osteoporosis.
methodsA retrospective analysis was conducted of 102 patients older than 50 years who underwent lumbar spine surgery at our institution from 2016 to 2024. Eligible patients underwent dual-energy x-ray absorptiometry (DXA), full-spine x-ray imaging, and computed tomography within 3 months before their surgery. CBR measurements were obtained by analyzing x-ray images for the inner and outer diameters of the femoral shaft 7 cm below the lesser trochanter. The Youden index based on
resultsThe cutoff value for CBR was 0.501, which was identified by analyzing BMD data from the lumbar spine and femoral neck regions. This cutoff demonstrated a strong correlation with low BMD scores, exhibiting a sensitivity of 0.656 and a specificity of 0.671 for identifying osteoporosis among the included patients. Additionally, CBR values negatively correlated with
conclusionCBR correlates with CLINICAL RELEVANCE: CBR facilitates early intervention and improves management in populations at high risk for bone fragility. LEVEL OF EVIDENCE: 3:
