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
backgroundPostoperative pain after breast surgery is common and can progress to chronic pain. Regional blocks like the erector spinae plane block (ESPB) could attenuate pain while limiting opioid consumption.
methodsWe searched PubMed, OneSearch, and Cochrane Library on May 2, 2025, for randomized controlled trials (2010–2025) evaluating the efficacy of an ESPB for postoperative pain in breast surgery. Thirteen trials (n = 856) met eligibility criteria. Pain (visual analogue or numeric rating scales) at 2, 4, 6, 12, and 24 h, cumulative 24-hour opioid consumption (converted to IV morphine equivalents), and time to first rescue analgesic were extracted. Medians and interquartile ranges (IQRs) were converted to means and standard deviations (SD) with the Wan method; pooled mean differences (MD) were calculated with inverse-variance random-effects models. Certainty was assessed using the GRADE approach; evidence profiles and a Summary of Findings table are provided.
resultsEleven trials were used for the pain analysis. ESPB lowered pain scores from 2 hours (MD -0.83 units, 95% confidence intervals (CI), -1.64 to -0.02) through 24 h (MD -0.45, -0.86 to -0.05). Heterogeneity was high (I2 > 95%). Five trials (n = 332) reported usable opioid data; ESPB reduced 24-hour opioid consumption by approximately − 2.1 mg IV morphine equivalents (-4.3 to 0.2, p = 0.07). Six trials (n = 402) showed ESPB delayed rescue analgesia by 3.64 h (0.71 to 6.56). Sensitivity analyses excluding high-risk studies yielded comparable results. Evidence certainty was moderate for pain, but low for opioid and rescue analgesia outcomes.
conclusionESPB provides modest yet clinically relevant reductions in pain for the first 24 h after breast surgery and prolongs the interval before additional analgesia is required, with a trend toward opioid sparing. Given its technical simplicity and favorable safety profile, the ESPB represents a practical addition to multimodal enhanced recovery pathways. Larger, head-to-head trials are needed to refine effect sizes and explore long-term outcomes.
