Efficacy and recovery of remimazolam versus midazolam in sedated upper gastrointestinal endoscopy: a multicenter randomized controlled trial in Japan (RECOVER 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
objectivesSedation is increasingly essential for gastrointestinal endoscopy. Remimazolam, an ultra-short-acting benzodiazepine, has a shorter pharmacokinetic half-life than midazolam. The aim of this study was to determine whether remimazolam provides superior procedural sedation in Japanese patients.
methodsThe cohort of this prospective, multicenter, randomized, single-blind controlled trial comprised adults (18-80 years) scheduled for sedated upper gastrointestinal endoscopy. Participants were randomized to remimazolam and midazolam groups. The primary outcome was the proportion of ambulatory patients 5 min after endoscopy. Secondary outcomes were successful pre-procedure sedation (Modified Observer's Assessment of Alertness/Sedation ≤ 4), dose of sedative to achieve sedation, time to ambulation, and adverse events.
resultsFrom October 2024 to January 2025, 40 patients were enrolled. After excluding two outliers 38 were analyzed (remimazolam, n = 20; midazolam, n = 18). Ambulation at 5 min occurred in 85.0% (17/20) of the remimazolam versus 0.0% (0/18) of the midazolam group (p < 0.0001). Mean time from procedure end to walking was 4.25 min (range 0.0-10.0) for remimazolam and 35.56 min (10.0-60.0) for midazolam (p < 0.0001). Pre-procedure sedation was successful (MOAA/S ≤ 4) in 100% of both groups. Mean doses to achieve sedation were 4.30 mg (3.0-7.0) for remimazolam and 3.11 mg (2.0-5.0) for midazolam (p = 0.003). Hypoxemia occurred in 5.0% of the remimazolam and 33.3% of the midazolam group (p = 0.038).
conclusionsIn upper gastrointestinal endoscopy, remimazolam achieved markedly faster recovery and a lower incidence of hypoxemia than midazolam. Rates of achieving target sedation were equivalent. These findings indicate remimazolam is an effective and potentially safer sedative option for Japanese patients undergoing endoscopy.
