Bone marrow hyperattenuation on CT for detection of hip fractures without cortical disruption and assessment of intertrochanteric extension in greater trochanter fractures.

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
purposeTo evaluate the diagnostic performance of bone marrow hyperattenuation (BMH) on CT for detecting fractures in patients without definite cortical disruption on CT and assessing the extent of intertrochanteric (IT) fracture extension in patients with suspected isolated greater trochanter fractures (IGTFs). MATERIALS AND
methodsThis retrospective study included two groups of patients aged ≥ 65 years undergoing CT for suspected hip fractures: the cortical disruption-negative group (without definite cortical disruption on CT) and the suspected IGTF group (with a cortical fracture confined to the greater trochanter on CT). BMH was defined as a visually appreciable, localized increase in bone marrow attenuation on CT. Three radiologists independently evaluated CT images. In the cortical disruption-negative group, BMH was visually assessed for fracture detection, using MRI or clinical follow-up as the reference standard. In the suspected IGTF group, visual assessment evaluated whether BMH extended ≥ 50% of the IT line, using MRI as the reference standard. Patients with bilaterally evaluable femora underwent ROI-based quantitative assessment. Diagnostic performance, agreement, ROC analysis, and reproducibility were analyzed.
resultsIn the cortical disruption-negative group (n = 57), visual BMH assessment showed median sensitivity and specificity of 90.5% and 97.2% for fracture detection, with almost perfect agreement (κ = 0.90). In the suspected IGTF group (n = 25), visual assessment showed median sensitivity and specificity of 86.7% and 80.0% for detecting IT extension ≥ 50%, with substantial agreement (κ = 0.72). In ROI assessment, performed in 50 and 16 patients, reader-specific AUCs were 0.720-0.935 for fracture detection and 0.945-1.000 for IT extension assessment; corresponding ICCs were 0.70 and 0.86.
conclusionBMH on CT allows fracture detection without definite cortical disruption and assessment of IT extension in suspected IGTFs, supporting its role as an adjunctive CT finding. Quantitative assessment may provide complementary information in selected patients.
