Radiation Exposure in Operatively Treated Pediatric Femur Fracture Patients.
Article in Journal of pediatric orthopedics. 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
backgroundChildren who sustain femur fractures are exposed to medical radiation as part of their treatment. In addition to standard radiographs and fluoroscopy, computerized tomography (CT) is a major source of ionizing radiation (IR). These patients frequently undergo CT scans during their treatment. The aim of the current study was to quantify the factors associated with greater IR exposure in children with operatively treated femur fractures and compare radiation exposure among those who received CT scans versus those who did not.
methodsThirty-eight patients below 18 years old with operatively treated traumatic femur fractures were included in the study. They fell into one of 2 groups: 1 received 1 or more CT scans (CT group), and the other did not receive a CT scan (non-CT scan). The 2 groups were then compared by total quantitative radiation exposure, age, BMI, location of the femur fracture, open versus closed fracture, and the presence versus absence of fracture displacement.
resultsThe effective dose of IR exposure that occurred within the operating room (OR) made up 75.7%±27.4% of the total IR exposure among all patients. Patients in the CT group had over a 5-fold greater quantitative cumulative IR exposure compared with the non-CT group ( P <0.0001). Furthermore, patients in the CT group were significantly older than ( P =0.004) and had a greater BMI ( P =0.045) than the non-CT group.
conclusionChildren with pediatric femur fractures often exceed what is considered a low level of radiation. There is a significant difference in radiation exposure between pediatric femur fracture patients who receive 1 or more CT scans compared with those who do not receive a CT scan. LEVEL OF EVIDENCE: Level III-retrospective cohort study.
