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

objectivesTo explore the dynamic pattern and physiological regulation of common carotid artery (CCA) blood flow during general anesthesia in elderly patients.

methodsA total of 193 elderly patients undergoing abdominal surgery were prospectively enrolled. Respiratory and hemodynamic variables and anesthetic depth of the patients were recorded throughout the perioperative period. CCA blood flow was measured at predefined time points using vector flow imaging. Heart rate, mean arterial pressure, end-tidal carbon dioxide, and bispectral index were included in a linear mixed-effects model, with patient ID as a random effect, to explore the physiological determinants of intraoperative CCA blood flow.

resultsCCA blood flow showed clear stage-related changes during general anesthesia. The mixed-effects model explained 52.0% of the variation in CCA blood flow (adjusted

conclusionsIntraoperative cerebral perfusion is not maintained by blood pressure alone but influenced jointly by ventilation, hemodynamic status, and anesthetic depth. Recognizing and managing these factors may help optimize cerebral perfusion during surgery.
