1 · What the graph read from 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.

2 · The registry

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

BACKGROUND AND

objectivesLocal and systemic inflammation is common after surgery and is associated with morbidity and mortality. Inflammatory cytokines have been implicated in cancer metastasis following cancer surgery. The present study aimed to analyze inflammatory cytokines levels after surgery under combined epidural/general anesthesia (EA + GA) vs. general anesthesia (GA).

methodsWe systematically searched PubMed, Central, EMBASE, CINAHL, Google Scholar, and Web of Science citation indexes for clinical studies (cancer and non-cancer surgery) comparing the two techniques. We carried out a meta-analysis to evaluate the postoperative plasma levels of cytokines, C-reactive protein (CRP), and cortisol levels.

resultsThe literature search was last updated on 2 January 2025. We identified a total of 21 studies which compared postoperative inflammatory mediators with EA plus GA compared to GA alone. EA plus GA was associated with significantly lower serum levels of IL-6, TNF-α, CRP, as well as cortisol and other pro-inflammatory cytokines. In cancer surgery, EA plus GA was also associated with lower postoperative cytokines.

conclusionsOur meta-analysis indicates that EA plus GA is associated with diminished postoperative inflammatory response. This offers an alternative explanation for the benefit of epidural analgesia on postoperative outcomes. Considering the link between postoperative inflammation and recurrence after cancer surgery, this is an area that warrants further research.
