Erector spinae plane block versus retrolaminar block for postoperative analgesia after breast surgery: a randomized controlled trial.
Trial report in Journal of anesthesia, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to 3 registered trials, which are not on this map. Cited by 22 papers, 3 of them syntheses 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.

Abstract
purposeThe newly introduced erector spinae plane block (ESPB) has given anesthesiologists an alternative regional anesthetic technique for thoracic analgesia. Although ESPB and retrolaminar block (RLB) have similar puncture sites, no clinical study comparing ESPB and RLB has been reported. The aim of this study was to compare ESPB and RLB in terms of analgesic efficacy in the context of multimodal analgesia following breast surgery.
methodsFifty female patients undergoing breast surgery under general anesthesia were randomly allocated to receive either ultrasound-guided ESPB or RLB with 20 mL of 0.375% levobupivacaine for postoperative analgesia. The primary outcome was analgesic efficacy in terms of time to first postoperative rescue analgesic after the block procedure. The secondary outcomes were consumption of remifentanil during anesthesia, pain intensity at rest for 24 h postoperatively, and occurrence of postoperative nausea and vomiting (PONV).
resultsAfter excluding five patients, 45 patients (22 and 23 patients in the ESPB and RLB group, respectively) were analyzed. Median time until the first postoperative rescue analgesic after the block procedure in the ESPB group was not significantly longer than that in the RLB group (8.6 [range 2.7-24] vs. 4.8 [3.0-24] h; P = 0.83). There was no significant difference in the consumption of remifentanil during anesthesia, pain intensity at rest for 24 h postoperatively, and occurrence of PONV between the two groups.
conclusionESPB is equivalent, and not superior, to RLB for postoperative analgesia after breast surgery when 20 mL of 0.375% levobupivacaine is injected at the fourth thoracic vertebra.
