Erector Spinae Plane Block Versus PECS Block Type II for Breast Surgery: A Randomized Controlled Trial.
Article in Anesthesiology and pain medicine, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06758765 (Comparison of the Effects of the Erector Spinae Plane Block and PECS I-II Blocks on Postoperative Opioid Consumption and Pain Scores of Patients After Breast-conserving Surgery), which is not on this map. Cited by 13 papers, 1 of them a synthesis that pooled 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.
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.

Abstract
Background: Regional anesthetic techniques are the primary analgesic techniques in breast cancer surgery. Novel techniques include the pectoralis (PECS) block and the erector spinae plane (ESP) block. Objectives: This study compared the analgesic efficacy of ultrasound-guided ESP and PECS-II blocks in patients undergoing unilateral modified radical mastectomy (MRM). Methods: The current prospective randomized controlled trial investigated 60 females scheduled for unilateral MRM under general anesthesia. The participants were randomized into two groups, namely a single-shot ESP block (n = 30) and a PECS-II block (n = 30). The ESP block was conducted at the level T4 using an in-plane approach. A volume of 20 ml of bupivacaine 0.25% was administered in both blocks. The outcome measures were total morphine consumption, analgesia duration, postoperative pain intensity, and nausea and vomiting. Results: More ESP participants required rescue morphine analgesia than those in the PECS group (P = 0.028). The ESP group showed significantly higher total morphine consumption (P = 0.005) and a shorter time to request analgesia (P = 0.003). Pain intensity was higher in the ESP group 1, 2, and 6 hours after the surgery. Conclusions: The PECS-II block is more effective in postoperative pain control after breast cancer surgery than the ESP block. It also prolongs the duration of analgesia and reduces the need for morphine 24 hours after the surgery.
