1 · What the graph read from 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.

2 · The registry

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

Post-traumatic brain contusions (PTBCs) are traditionally considered primary injuries and can increase in size, generate perilesional edema, cause mass effect, induce neurological deterioration, and cause death. Most patients experience a progressive increase in pericontusional edema, and nearly half, an increase in the hemorrhagic component itself. The underlying molecular pathophysiology of contusion-induced brain edema and hemorrhagic progression remains poorly understood. The aim of this study was to investigate sulfonylurea 1/transient receptor potential melastatin 4 (SUR1-TRPM4) ion channel SUR1 expression in various cell types (neurons, astrocytes, endothelial cells, microglia, macrophages, and neutrophils) of human brain contusions and whether SUR1 up-regulation was related to time postinjury. Double immunolabeling of SUR1 and cell-type- specific proteins was performed in 26 specimens from traumatic brain injury patients whose lesions were surgically evacuated. Three samples from limited brain resections performed for accessing extra-axial skull-base tumors or intraventricular lesions were controls. We found SUR1 was significantly overexpresed in all cell types and was especially prominent in neurons and endothelial cells (ECs). The temporal pattern depended on cell type: 1) In neurons, SUR1 increased within 48 h of injury and stabilized thereafter; 2) in ECs, there was no trend; 3) in glial cells and microglia/macrophages, a moderate increase was observed over time; and 4) in neutrophils, it decreased with time. Our results suggest that up-regulation of SUR1 in humans point to this channel as one of the important molecular players in the pathophysiology of PTBCs. Our findings reveal opportunities to act therapeutically on the mechanisms of growth of traumatic contusions and therefore reduce the number of patients with neurological deterioration and poor neurological outcomes.
