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
Purpose: The current study aimed to compare the effects of norepinephrine and phenylephrine on tissue oxygenation and clinical outcomes in Moyamoya disease patients. Patients and Methods: Sixty patients scheduled for superficial temporal artery-middle cerebral artery bypass were randomly assigned to either the norepinephrine group or the phenylephrine group. Standard doses of norepinephrine or phenylephrine were infused during surgery to maintain blood pressure fluctuating within ± 10% of baseline values. Cerebral oxygenation, muscle oxygenation, cardiac output, and urine volume were recorded at several timepoints: Before preoxygenation, After intubation, Skin cutting, Superficial temporal artery exposing, Middle cerebral artery exposing, and End of the surgery. Additionally, blood samples were collected from the superior vena cava and radial artery for blood gas analysis, to assess central venous oxygen saturation, blood lactate and calculate oxygen extraction rate. Length of hospital stay, incidence of neurological complications during hospitalization and mortality within 90 days were also recorded. Results: Compared with phenylephrine group, the norepinephrine group exhibited significantly higher cerebral oxygenation, muscle oxygenation and cardiac output at Superficial temporal artery exposing, Middle cerebral artery exposing, and End of the surgery ( Conclusion: The use of norepinephrine, in contrast to phenylephrine, for managing hypotension during superficial temporal artery-middle cerebral artery bypass significantly enhances tissue oxygenation, which may be related to the effective maintenance of cardiac output by norepinephrine.
