Does routine repeat imaging change management in high-grade renal trauma? Results from three level 1 trauma centers.
Article in World journal of urology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled it.
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
purposeGuidelines call for routine reimaging of Grade 4-5 renal injuries at 48-72 h. The aim of the current study is to evaluate the clinical utility of computed tomography (CT) reimaging in high-grade renal injuries. MATERIALS AND
methodsWe assembled data on 216 trauma patients with high-grade renal trauma at three level 1 trauma centers over a 19-year span between 1999 and 2017 in retrospectively collected trauma database. Demographic, radiographic, and clinical characteristics of patients were retrospectively reviewed.
resultsIn total, 151 cases were Grade 4 renal injuries, and 65 were Grade 5 renal injuries. 53.6% (81) Grade 4 and 15.4% (10) Grade 5 renal injuries were initially managed conservatively. Of the 6 asymptomatic cases where repeat imaging resulted in intervention, 100% had collecting system injuries at initial imaging. Collecting system injuries were only present in 42.9% of cases where routine repeat imaging did not trigger surgical intervention. Collecting system injury at the time of initial imaging was a statistically significant predictor of routine repeat imaging triggering surgical intervention (p = 0.022). Trauma grade and the presence of vascular injury were not significant predictors of intervention after repeat imaging in asymptomatic patients.
conclusionIn asymptomatic patients with high-grade renal trauma, the number needed to image is approximately one in eight (12.5%) to identify need for surgical intervention. There is potentially room to improve criteria for routine renal imaging in high-grade renal trauma based on the more predictive imaging finding of collecting system injury.
