Erector Spinae Plane versus Pectoralis Nerve Block for Mastectomy in Cancer Patients: A Retrospective, Multicenter Cohort Study.

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
Background: Mastectomy patients require effective acute postoperative pain management. Regional anesthesia techniques such as fascial plane blocks are important pain treatment modalities to address pain control. This study compared the effects of the erector spinae plane (ESP) block versus the pectoralis nerve (PECS) block in providing postoperative analgesia for mastectomy patients. Methods: This retrospective study included 517 breast cancer patients undergoing mastectomy from 2017 to 2020, with 428 receiving a PECS block and 89 an ESP block. The primary outcome examined was total opioid use during hospital stay measured in morphine milligram equivalents (MME). Secondary outcomes included length of hospital stay, post-anesthesia care unit (PACU) pain scores, PACU postoperative nausea and vomiting (PONV), 30-day readmission rates, and development of postmastectomy pain within six months of surgery. Results: No significant difference in median total opioid use between the ESP (53 MME (IQR: 38-80 MME)) and PECS (60 MME (IQR: 30-82.5 MME)) groups. Multivariable analysis confirmed no difference in total opioid consumption. There was no significant difference between the two groups in PACU average and maximum pain scores, PACU PONV, hospital length of stay, 30-day hospital readmission, and development of postmastectomy pain within six months of surgery. Conclusion: Compared to the PECS block, the ESP block demonstrated no significant difference in acute pain outcomes and recovery in patients undergoing mastectomy for breast cancer, with similar hospital discharge times and long-term outcomes.
