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

Objectives: Cerebral microbleeds (CMBs), which present as foci of hypointensities on T2*-weighted Magnetic Resonance Imaging (MRI) are associated with weakened vessel walls. CMBs are also a frequent finding in traumatic brain injury (TBI) in association with poor outcome. We investigated whether a combination of susceptibility weighted imaging (SWI) and dynamic contrast enhanced (DCE) MRI could accurately identify characteristics of CMBs that are most relevant to TBI. Materials and Methods: Thirty TBI patients were recruited from a neurosurgical unit. We acquired structural three-dimensional T1-weighted, T2-weighted dark fluid, SWI, and DCE-MRI images on a 3T MRI. DCE-MRI data was fitted for a linear graphic (Patlak-Gjedde) model to calculate voxel-wise volume transfer constant (K Results: More severe TBI was associated with CMBs exhibiting leaky BBB as quantified by DCE-MRI. Higher blood levels of interferon gamma (IFN-γ) were associated with lower number of CMBs in TBI patients at more than 8 days post-TBI. Discussion: combined DCE-MRI and SWI confirmed that CMBs with leaky BBBs are more prevalent in moderate-severe TBIs compared. Higher levels of IFN-γ appeared to have been associated with fewer CMBs in the sub-acute stage of TBI.
