Advanced Imaging Techniques Use in Giant Cell Arteritis Diagnosis: The Experience at Walter Reed National Military Medical Center.
Article in Federal practitioner : for the health care professionals of the VA, DoD, and PHS, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: If not diagnosed in a timely manner, giant cell arteritis (GCA) can lead to significant morbidity. The 1990 American College of Rheumatology criteria for GCA do not include screening technologies, though proposed criteria do. Methods: This study evaluated current clinical practices in diagnosing GCA and the use of screening technologies such as ultrasound, magnetic resonance imaging (MRI), computed tomography (CT), and positron emission tomography (PET). A retrospective chart review was conducted of patients who underwent diagnostic testing for GCA from 2016 through 2022 at Walter Reed National Military Medical Center. Results: Seventy-eight charts were reviewed; 42 patients (54%) had a GCA diagnosis and 36 patients (46%) were GCA negative. Temporal artery biopsy was positive for 19 (45%) patients. Most patients did not undergo bilateral temporal artery biopsies despite recommendations. Among those diagnosed with GCA, 29 (69%) underwent biopsy, and 25 (60%) received diagnostic imaging. Conclusions: Evidence supports the use of additional screening tools beyond clinical and laboratory data to improve the diagnostic yield of temporal artery biopsy. Initial screening with ultrasound is a cost-effective and widely available modality that may reduce the risk of false-negative biopsy results. Other tests include vascular MRI/CT and PET. The target goal is to increase the diagnostic yield of temporal artery biopsies to ≥ 70%.
