Effects of Remimazolam Anesthesia in Patients Undergoing Deep Inferior Epigastric Perforator Flap Reconstruction for Breast Cancer: A Retrospective Cohort 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
In deep inferior epigastric perforator (DIEP) free flap surgery for breast reconstruction, vasopressors may cause vasoconstriction and impair flap perfusion, potentially increasing the risk of complications. In this study, we aimed to determine the effects of remimazolam anesthesia on intraoperative vasopressor requirements and postoperative outcomes in patients undergoing DIEP flap reconstruction compared with conventional anesthesia. We conducted a retrospective cohort study of DIEP flap procedures performed between March 2021 and March 2022 at a single institution. Patients were stratified according to the anesthetic regimen (sevoflurane, propofol, and remimazolam). The primary outcome was the total intraoperative norepinephrine requirement. Among 102 initially identified patients, 75 met the inclusion criteria. The remimazolam group required significantly less norepinephrine than the sevoflurane and propofol groups (202.1 µg vs. 1558.6 µg and 926.6 µg, respectively;
