Anesthesia for Patients Who Self-Report Cannabis (Marijuana) Use Before Esophagogastroduodenoscopy: A Retrospective Review.
Article in AANA journal, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06567873 (Assessment of Preoperative Gastric Content With Ultrasound in Patients Reporting Cannabis Use), which is not on this map. Cited by 12 papers, 1 of them a synthesis that pooled 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.
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.

Abstract
Increasing numbers of patients are using cannabis before procedures that require anesthesia. This study set out to examine the impact of cannabis use on anesthetic agent requirements, associated cardiac and respiratory morbidity, and overall satisfaction levels in patients undergoing esophagogastroduodenoscopy (EGD). This involved a retrospective review of patients undergoing EGD at a single center. Fortyseven, self-reported cannabis users were identified and 23 were successfully cross-matched with control participants for comparison purposes. The Wilcoxon signed rank test was used to evaluate differences in propofol administration between the 2 groups, and the McNemar test was used to test for differences in fentanyl and ketamine administration. No statistically significant differences were observed in propofol, fentanyl, or ketamine administration in the cannabis group compared with the control group. No adverse cardiac or respiratory events were reported within 30 days for either group. This study was specific to EGD procedures of short duration, and larger studies are needed to confirm results of no consequence in cannabis users undergoing anesthesia. Future studies should consider cannabis users who undergo anesthesia for diverse procedure types of various durations.
