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

objectiveThis meta-analysis investigated the analgesic effects of erector spinae plane block (ESPB) in patients undergoing breast surgery.

methodsPubMed, Embase, Web of Science, and the Cochrane Library were searched from database establishment to January 31, 2020. Two reviewers independently extracted the data. The primary outcomes were pain scores and opioid consumption during the first 24 hours after surgery. The risk of bias of the included studies was assessed according to the Cochrane Handbook.

resultsSix randomized controlled trials of 415 patients were included. Compared with the control value, the pain score was significantly lower in the ESPB group at different time points postoperatively. Patients who underwent ESPB required lower opioid consumption (standardized mean difference = -2.02, 95% confidence interval [CI] = -2.85 to -1.20,

conclusionsESPB significantly alleviated pain and reduced opioid consumption after breast surgery. Further research is needed to expand its clinical application.PROSPERO registration number CRD42020167900.
