Could the perioperative use of opioids influence cancer outcomes after surgery? A scoping review protocol.
Article in BMJ open, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundDuring and after general anaesthesia, opioids are commonly used for pain treatment. Since preclinical studies underlined the potential immunosuppressive activity of these drugs, it was postulated that their perioperative administration could influence cancer outcomes after surgery. Nevertheless, clinical data have been extrapolated mainly from retrospective analyses. Consequently, the precise link between perioperative opioid use and cancer recurrence/metastasis or cancer-related mortality/morbidity is still an unsolved issue. METHODS AND ANALYSIS: This scoping review is planned to follow the Joanna Briggs Institute recommendations. The authors will conduct a literature review through the PRISMA statement using PubMed and EMBASE databases; the Grey literature will be explored using Google Scholar and Conference Proceedings Citation Index (via Web of Science). The search strategy will be limited to articles published in the English language and to human studies. The database searches are planned from the inception to January 2022. Two reviewers will independently screen titles and abstracts, followed by a full-text screening of potentially relevant articles with standardised data extraction. Any disagreement for the inclusion between the two reviewers will be discussed with a third reviewer. ETHICS AND DISSEMINATION: The review aims to map the available literature, focusing on a possible association between perioperative opioid use and cancer outcomes in patients undergoing surgery. The proposed approach will be useful to identify and analyse the knowledge gap in the field and serve as a prerequisite for future research.
