Effects of erector spinae plane block versus local infiltration analgesia for abdominal surgeries: a protocol for systematic review and meta-analysis.
Article in BMJ open, 2025. 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
introductionErector spinae plane (ESP) block and local infiltration analgesia (LIA) are widely used to control postoperative pain after abdominal surgery. An increasing number of randomised controlled trials (RCTs) have compared the analgesic effects of ESP block and LIA after abdominal surgery, but the results are inconsistent. This protocol of a systematic review and meta-analysis aims to determine whether the analgesic effects of ESP block are better than those of LIA in abdominal surgeries. METHODS AND ANALYSIS: Two authors will independently search PubMed, EMBASE, Web of Science and the Cochrane Library from their inception to 15 August 2025. RCTs that compared the analgesic effects of ESP block with LIA for abdominal surgeries will be included. The primary outcome will be opioid consumption over 24 hours postoperatively. The secondary outcomes will include the time to first rescue analgesia, pain intensity score and incidence of adverse effects. RevMan V.5.4 software will be used for statistical analysis. ETHICS AND DISSEMINATION: Ethical approval is not applicable. The results of this study will be publicly published in one peer-reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42024598176.
