Predictors and Time-Based Hospital Mortality in Patients with Isolated and Polytrauma Brain Injuries.
Observational study in World journal of surgery, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
backgroundTraumatic brain injury (TBI) is a major cause of morbidity and mortality worldwide. We studied the predictors and time-based mortality in patients with isolated and polytrauma brain injuries in a rapidly developing country. We hypothesized that TBI-related 30-day mortality is decreasing over time.
methodsA retrospective analysis was conducted for all patients with moderate-to-severe TBI who were admitted directly to a level 1 trauma center between 2010 and 2014. Patient's data were analyzed and compared according to survival (survived vs. not survived), time (early death [2 days], intermediate [3-7 days] versus late [>7 days]) post-injury, and type (polytrauma vs. isolated TBI). Cox proportional hazards models were performed for the predictors of mortality.
resultsA total of 810 patients were admitted with moderate-to-severe TBI with a median age of 27 years. Traffic-related injury was the main mechanism of TBI (65%). Isolated TBIs represented 22.6% of cases and 56% had head AIS >3. The overall mortality rate was 27%, and most of deaths occurred in the intermediate (40%) and early period (38%). The incidence of TBI was greater in patients aged 21-30 years but the mortality was proportionately higher among elderly. The average annual incidence was 8.43 per 100,000 population with an overall mortality of 2.28 per 100,000 population. Kaplan-Meier curves showed that polytrauma had greater mortality than isolated TBI. However, Cox survival analysis showed that age [Hazard ratio (HR) 1.02], scene GCS (HR 0.86),subarachnoid hemorrhage (HR 1.7), and blood transfusion amount (HR 1.03) were the predictors of mortality regardless of being polytrauma or isolated TBI after controlling for 14 relevant covariates.
conclusionsThe 30-day survival in patients with TBI is improving over the years in Qatar; however, the mortality remains high in the elderly males. The majority of deaths occurred within a week after the injury. Further studies are needed to assess the long-term survival in patients with moderate-to-severe TBI.
