The Effects of Cannabis Use on Postoperative Outcomes after Spinal Fusion for Adolescent Idiopathic Scoliosis.
Article in Journal of the American Academy of Orthopaedic Surgeons. Global research & reviews, 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
STUDY
designThis was a retrospective matched-cohort study.
objectiveThere is limited information about the effects of cannabis on patients undergoing surgery for adolescent idiopathic scoliosis (AIS). This study investigated if self-reported cannabis use is associated with postoperative pain, opioid use, and complication rate after spinal fusion.
methodsAIS patients with self-reported preoperative cannabis use were matched to control subjects with no history of cannabis use. Matching criteria included age at surgery, sex, initial curve magnitude, curve type, and number of levels fused. Inclusion required an AIS diagnosis and spinal fusion at a single center from 2011 to 2019. Intraoperative outcomes, pain scores, medication use, and postoperative complications were collected. Follow-up duration was 1 month.
resultsThirteen cannabis positive patients with AIS were matched to 65 controls (median age 18.1, 65% males). A significant increase was observed in surgical time per level fused for cannabis patients (33 vs 28 min, P = 0.03), but this was insignificant when controlling for the propensity score (P = 0.08). No significant differences were observed in intraoperative outcomes, pain scores, pain medication use, discharge pain medication amounts, length-of-stay, curve correction, or complication rate.
conclusionPreoperative cannabis use was not associated with differences in surgical safety, anesthesia risk, inpatient pain, opioid use, and postoperative complications to the interval of the first postoperative appointment. Future prospective research is needed to determine the effects of cannabis on long-term follow-up from AIS spinal fusion.
