Bone marrow edema around the hip in non-traumatic pain: dual-energy CT vs MRI.
Article in European radiology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 papers.
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
objectivesTo evaluate the diagnostic accuracy of dual-energy computed tomography (DECT) in identifying bone marrow edema (BME) around the hip joint in non-traumatic patients.
methodsThis prospective IRB-approved study was conducted between January 2019 and October 2019 and included 59 consecutive patients (18 males, 41 females; mean age 61.5 years, range 32-82) who were assessed by DECT and magnetic resonance imaging (MRI) within a 5-day period. Diagnostic accuracy values for diagnosing BME on a per-patient and on a per-partition-basis analysis were calculated for DECT images by two readers (R1 and R2, with 15 and 10 years of experience, respectively), using MRI as reference for diagnosis. Inter-observer agreements were calculated with k-statistics. A p value of < 0.05 was considered as statistically significant.
resultsMRI depicted BME in 44/59 patients (74.58%), with the involvement of 83/708 (11.72%) partitions. The sensitivity, specificity, and accuracy of R1 and R2 were 95.45% (42/44), 86.67% (13/15), and 93.22% (55/59) for R1, and 86.36% (38/44), 80.00% (12/15), and 84.75% (50/59) for R2. For both readers, the BME detection rate was higher in patients with severe edema (100%) in comparison to patients with mild edema (91.30% and 73.91%). In the partition-basis analysis, sensitivity, specificity, and accuracy ranges were 33.3 to 100%, 91.84 to 100%, and 88.14 to 100%, respectively. The inter-observer agreement for patients' analysis was substantial (k = 0.7065), whereas for partition analysis ranged from fair (k = 0.2976) to near-perfect (k = 1.000).
conclusionDECT can accurately identify BME around the hip joint, in comparison to MRI. KEY POINTS: • DECT can accurately identify bone marrow edema around the hip joint in a cohort of non-traumatic patients. • The detection of bone marrow edema by means of DECT may help the radiologist to identify associated findings, including avascular necrosis of the femoral head and insufficiency or stress fractures. • In cases of patients suffering from groin pain with bone marrow edema identified by DECT, the concurrent reading of high-resolution conventional CT images may increase the confidence of diagnosis and/or reduce the reading time.
