Impact of cannabis use and tobacco smoking on outcomes of open carpal tunnel release surgery: a nationwide study in the United States.
Article in Archives of orthopaedic and trauma surgery, 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
purposeTo evaluate the impact of cannabis use, tobacco smoking, and their concurrent use on postoperative complications following open carpal tunnel release (CTR) using a nationwide database.
methodsA retrospective cohort study was conducted using the PearlDiver database (2010-2022) to identify adult patients who underwent open CTR. Patients were categorized into four groups: cannabis-only users (n = 800), tobacco-only users (n = 167,803), concurrent users (n = 3529), and non-users (n = 167,803 matched controls). Postoperative complications, surgical site infection, wound disruption, joint stiffness, and complex regional pain syndrome, were assessed at 6 weeks and 3 months postoperatively.
resultsAt 6 weeks and 3 months, surgical site infection was more common among concurrent cannabis and tobacco users, cannabis-only users, and tobacco-only users. Wound disruption occurred more frequently in concurrent users and tobacco-only users, but not in cannabis-only users. Complex regional pain syndrome was associated only with tobacco use. No association was found between any substance use and joint stiffness.
conclusionCannabis use, tobacco smoking, and especially concurrent use increase the risk of surgical site infection and wound disruption following open CTR. Tobacco use is independently associated with complex regional pain syndrome, while cannabis may have a protective effect. These findings emphasize the need for preoperative screening and patient education. TYPE OF STUDY/LEVEL OF EVIDENCE: Retrospective cohort study/level III.
