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

Background: Ciprofol is increasingly used in surgical procedures, and anesthesiologists have observed that it provides deeper sedation compared to propofol. However, it remains unclear whether the use of ciprofol alone, without combining opioids, is sufficient for upper gastrointestinal endoscopy. This study aims to address this question. Objective: To determine whether ciprofol alone is non-inferior to ciprofol combined with fentanyl regarding sedation success and safety. Methods: In this randomized, double-blind trial, 344 adult patients (ASA I-II, aged 18-70 years) undergoing elective upper gastrointestinal endoscopy were randomized to receive either ciprofol with saline (CS group) or ciprofol with fentanyl (CF group). Participants in both groups received an initial ciprofol dose of (0.4 mg/kg). The CF group received (1 µg/kg) intravenously before ciprofol administration, while the CS group received an equivalent volume of saline. Additional ciprofol doses (0.15-0.30 mg/kg) were administered as needed. The primary outcome was sedation success, defined as procedure completion with no more than two additional ciprofol doses within any 5-minute interval. Secondary outcomes included the incidence of hypotension and hypoxemia, as well as adverse events. Results: Sedation success rates were 99.4% for CS and 100% for CF, demonstrating non-inferiority (difference: -0.6%, 95% CI: -0.02, 0.01). The CS group had lower respiratory depression rates and better hemodynamic stability but higher intraoperative coughing (18.1% vs 2.9%, P=0.01). Induction and recovery times were slightly longer in the CS group, and postoperative dizziness was more common (15.2% vs 7%, P=0.03). Conclusion: Ciprofol alone is non-inferior to ciprofol with fentanyl for sedation in upper gastrointestinal endoscopy and offers advantages in respiratory and hemodynamic stability. However, it is associated with increased coughing, minor delays in induction and recovery, and more postoperative dizziness.
