Topography of the hyperintense vessel sign on fluid-attenuated inversion recovery represents cerebral hemodynamics in middle cerebral artery occlusion: a CT perfusion study.

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
purposeWhether the topography of fluid-attenuated inversion recovery hyperintense vessel sign (FHVs) can serve as a measure of cerebral hemodynamic stress remains unclear. We hypothesized that FHVs topography represents different cerebral hemodynamic status, as assessed by CT perfusion (CTP).
methodsWe retrospectively reviewed 75 patients with acute middle cerebral artery (MCA) occlusion who underwent MR imaging and CTP. The FHVs topography included FHVs inside the diffusion-weighted imaging (DWI) lesion (FHVs in-group), FHVs outside the DWI lesion (FHVs out-group), and FHVs distributed inside and outside the DWI lesion (FHVs all-group). FHVs scores were assessed by the Alberta stroke program early computed tomography score (ASPECT) territories. Cerebral hemodynamic status was evaluated by relative (r) CTP parameters. Cerebral hemodynamic status was analyzed with respect to different FHVs topographies and FHVs scores.
resultsHemodynamic impairment was present in all patients, with the following mean rCTP parameters: rCBF, 0.77 ± 0.23; rCBV, 1.06 ± 0.32; and rMTT, 1.52 ± 0.60. Comparison of the rCTP parameters among the three groups, rCBF and rCBV (rCBF, P < 0.001; rCBV, P < 0.001) in the FHVs out-group and the FHVs all-group (rCBF, P = 0.001; rCBV, P < 0.001), were significantly higher than that in the FHVs in-group. Similarly, CTA collateral grade in the FHVs in-group was significantly lower than those in the FHVs out-group and FHVs all-group (P < 0.001). No significant difference was found in rCTP parameters between different FHVs scores.
conclusionThe different FHVs topographies represented different cerebral hemodynamic status. FHVs topography may serve as a surrogate for patient selection for reperfusion therapy whenever perfusion data are unavailable.
