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
Introduction: Propofol may induce emotional impairment like euphoria and elation. Previous studies have demonstrated that emotional impairment can injure social cognition like emotion recognition and decision-making abilities. Therefore, this study is designed to investigate the effects of propofol anesthesia on facial emotion recognition (FER) and delay discounting behavior. Method: Patients underwent diagnostic gastrointestinal endoscopy (GI) with propofol anesthesia in this prospective cohort observational study. Prior to and following the procedure (approximately 30 min afterwards), patients were asked to select the word that best describes the presented facial photographs displaying happiness, anger, and neutral expressions. Additionally, Monetary Choice Questionnaire-9 was used to assess delay discounting. Results: Within a cohort of 87 patients, 11 patients (12.6%) met the criterion of FER deficit post-GI. The FER of anger exhibited significant differences between pre- and post-GI, considering both the correct (52.6%) and incorrect (24.3%) recognition. There was a positive identification bias for FER after propofol anesthesia: mistaking anger ( Conclusion: The study demonstrates that propofol anesthesia during GI endoscopy selectively impairs the recognition of anger facial expressions while leaving the recognition of happiness and delay discounting unaffected at a short-term postoperative observation. Additionally, the recognition of anger and neutral facial expressions exhibited a tendency towards a positive bias.
