1 · What the graph read from 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

objectiveErector spinae plane (ESP) block is an alternative to neuraxial block for post-surgical pain in nephrectomy patients. However, no clinical trial has directly compared ESP block with a control group.

methodsIn a single-center, double-blind randomized comparative trial, patients undergoing nephrectomy with a subcostal flank incision under general anesthesia were divided into the following two groups: ESP block group (ESP block before anesthesia) and non-ESP (control) group (no intervention). The primary outcome measure was pain score (Numeric Rating Scale [NRS] 0 to 10). Secondary outcomes were postoperative opiate use, anesthetic and surgical complications, length of hospital stay, and patient-reported outcomes.

resultsPostoperatively (0 to 24 hours), the ESP block group experienced less pain and had lower NRS pain scores 0 to 24 hours postoperatively than the non-ESP group. Opioid consumption and the number of rescue analgesic doses decreased significantly in the ESP group compared with the non-ESP group. Patient-Reported Outcomes Information System (Quality of Recovery-15) scores significantly improved in the ESP group compared with the non-ESP block group.

conclusionsPatients receiving an ESP block for intraoperative and postoperative analgesia during radical nephrectomies experienced less postoperative pain 0 to 24 hours compared with the non-ESP group.
