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
We describe here a novel yet very simple technique, called microguidewire-assist (MGA) manoeuvre, for coil embolisation of unruptured intracranial aneurysms. A 79-year-old woman with a small, broad-necked middle cerebral artery (MCA) bifurcation aneurysm that incorporated the orifice of the acute-angled M2 superior trunk underwent coil embolisation. Since the balloon assist technique was not feasible, we inserted and retained only the microguidewire through M1 to the M2 superior trunk; subsequently, with appropriate use of the microguidewire, coil embolisation was completed. The MGA manoeuvre resulted in slight vessel straightening and subsequent changes in the angulation of the aneurysmal neck, with which stable placement of the platinum coil was successfully accomplished. For coil embolisation of small, broad-necked MCA aneurysms that partially straddle the M2 trunk, this manoeuvre might provide an effective therapeutic alternative if other techniques are not feasible.
