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.

2 · The registry

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

purposeBreast-conserving surgery (BCS) is a surgical method designed to minimize intraoperative tissue injury. Although this technique is minimally invasive, it can cause significant postoperative pain and may be a risk factor for persistent pain. Erector spinae plane block (ESPB) is an easy interfascial plane block for analgesia in patients undergoing breast surgery. The primary outcome was the numeric rating scale scores measured separately on the breast and axilla. Secondary outcomes included correlation between pain score and skin sensitivity test.

methodsForty patients were divided into 2 groups (ESPB group and control group). Patients in the ESPB group received an ESPB 30 minutes before the induction of general anesthesia, whereas patients in the control group did not receive any regional analgesia during the perioperative period.

resultsMedian pain scores of the breast were significantly lower in the ESPB group than that in the control group at 12, 24, and 48 hours after surgery. However, the median pain scores of the axilla were not significantly different between the groups, and the pain score was unrelated to skin sensitivity.

conclusionESPB can effectively alleviate acute postoperative pain with an opioid-sparing analgesic technique in patients undergoing BCS, and a strong correlation is lacking between pain scores and skin sensitivity test.
