Assessment of donor-vessel after STA-MCA bypass for moyamoya disease using handheld Doppler to confirm bypass patency and predict perioperative hyperperfusion.

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
The study included 12 hemispheres of 9 patients with moyamoya disease who underwent direct-indirect revascularization. The parameters (peak systolic velocity (PSV), mean flow velocity (MV), resistance index (RI), flow volume (FV)) of the superficial temporal artery (STA) on the operated side were measured using a handheld Doppler before and after surgery in all the patients. The examination was conducted in a similar manner on postoperative day (POD)1 on 9 sides of 7 patients except for 3 sides of the first 2 patients. Patency of the superficial temporal artery-middle cerebral artery (STA-MCA) bypass was confirmed by magnetic resonance angiography (MRA) performed on all 12 sides of 9 patients within the first 2 PODs. There was a statistically significant increase in the PSV (
