Opportunities to Reduce CT Radiation Exposure, Experience Over 5 Years at the NIH Clinical Center.
Article in Radiation protection dosimetry, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Our current study was undertaken in order to compare CT exposures during various dose-reduction initiatives at the National Institutes of Health Clinical center, to show trends in exposure reduction over a 5-y period, and to provide benchmarks that other facilities may use. Using an in-house extraction tool (Radiation Exposure Extraction Engine), we derived CT exposure data from Digital Imaging and Communications in Medicine (DICOM) headers over 5 y. We present parameters used and compare most common exams between 2010 and 2015. During a period of exposure-reduction initiatives, data of 79 396 exams from nine CT scanners on 87 scan protocols were analyzed. Adult chest exposures were reduced 53% and chest, abdomen and pelvis exams were reduced 43% (p < 0.001). Only extremity exams did not show significantly reduced exposure. Collecting data over several years allowed us to confirm and compare several initiatives. We demonstrated significant exposure reductions during continued reduction efforts on common exams. Our results may provide benchmarks for similar centers.
