Oliceridine combined with propofol-etomidate sedation in geriatric outpatients undergoing painless gastroscopy: study protocol for a randomized controlled trial.
Article in BMC geriatrics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionOliceridine is a novel G-protein selective µ-agonist that has been reported to provide better analgesia and safety than conventional opioids. The purpose of this study is to explore the efficacy and safety of oliceridine combined with propofol-etomidate(PE) sedation in geriatric outpatients undergoing painless gastroscopy.
methodsThis prospective, single-center, double-blinded, randomized controlled trial will be conducted at a tertiary A hospital and will enroll one hundred twelve geriatric outpatients undergoing painless gastroscopy. Eligible participants will be randomly assigned to either the experimental group or the control group.The experimental group will receive oliceridine combined with PE sedation, while the control group will receive dezocine combined with PE sedation.The primary efficacy and safety outcomes will be the use of PE sedation and the occurrence of adverse events during painless gastroscopy. Secondary outcomes will include hemodynamic parameters during painless gastroscopy and adverse events during the post-anaesthesia care unit (PACU) stay. Exploratory outcomes will encompass gastroscopy time; time to awakening in the PACU; length of stay in the PACU; pain score, sedation score, and modified Aldrete score at PACU discharge; endoscopist satisfaction; patient satisfaction; and the readmission rate. DISSCUSION: We hypothesize that oliceridine combined with PE sedation will provide more effective analgesia with improved safety. The findings of this trial will furnish helpful clinical evidence and guidance for the novel selection of analgesics for geriatric outpatients undergoing painless gastroscopy.
