Effects of establishing a trauma center on the mortality rate among injured pediatric patients in Japan.
Trial report in PloS one, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers, 2 of them syntheses 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
introductionIt remains unclear whether trauma centers are effective for the treatment of injured pediatric patients. The aim of this study was to evaluate children's mortality before and after the establishment a trauma center by using standard mortality ratios (SMR) and a modified observed-expected chart.
methodsThis was a single center, retrospective chart review study that included injured pediatric patients (age <16 years) who were transported to our trauma center by the emergency medical services from 2012 to 2016 in Japan.
resultsOur study included 143 subjects: 45 (31%) were preschoolers aged < 6 years, and 43 (30%) had an injury severity score (ISS) ≥ 16. After the trauma centers established, the number of patients increased (70% increase per month), as did the number of the patients with an ISS of 41-75. The percentage of indirect transportations was significantly higher in the trauma center than in the non-trauma center (49% vs. 28%; p < 0.05). The SMR was significantly lower in the trauma-center than in the non-trauma center (0.461 vs. 0.589; p < 0.05). The mean value of the modified observed-expected chart was significantly higher in the trauma-center than in the non-trauma center (4.6 vs. 2.3; p < 0.05). For the patients who were directly transferred to our center, the transfer distance was greater in the trauma-center than in the non-trauma center (6.8 vs. 6.2 km; p < 0.05). The time interval from hospital admission to initiation of computed tomography (15.5 vs. 33 minutes; p < 0.05) and to definitive care (44 vs. 64.5 minutes; p < 0.05) decreased in the after group compared to the non-trauma center.
conclusionsThe results of our study revealed that the centralization of pediatric injured pediatric patients in trauma centers improved the mortality rate in this population in Japan.
