Analgesic efficacy of uni-level erector spinae plane block in breast cancer surgery patients: a systematic review and Meta-analysis.
Synthesis in BMC anesthesiology, 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
backgroundSurgery remains the cornerstone of management in breast cancer patients. Regional anesthesia techniques, such as the erector spinae plane block (ESPB), have emerged as adjuncts to standard therapy for postoperative pain control.
methodsStudies comparing ESPB and standard procedure of general anesthesia and opioids were included. Primary outcomes were postoperative pain scores, analgesia duration, and postoperative morphine consumption.
resultsVAS pain scores were significantly reduced with the ESPB group. Similarly, longer analgesia duration (MD 7.03, 95%CI 4.92, 9.14, P < 0.0001), and lower postoperative morphine consumption (MD -5.77; 95% CI, -7.89, -3.65; P < 0.0001) were observed in the ESPB group. NRS pain scores at 24 h, intraoperative fentanyl, and postoperative tramadol consumption also decreased with ESPB. No significant differences were observed for NRS scores at 12 h. However, heterogeneity was high and most of the included studies had high or unclear risk of bias.
conclusionESPB may reduce opioid consumption and postoperative pain scores compared to the control groups. However, these results should be taken cautiously, due to the high risk of bias among the included studies and low certainty.
