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

BACKGROUND AND

aimsRegional anaesthesia has been used to reduce acute post-operative pain as well as opioid-related side effects in breast cancer surgery. Erector spinae plane (ESP) block is a relatively new fascial plane block being tried in various surgical procedures. Our study is a double-blind randomised trial, designed to prove the efficacy of this block in breast surgeries.

methodsSeventy female patients scheduled for unilateral breast surgery were enroled in this prospective, randomised, double-blind study. Patients were randomised to group A and group B. All patients received general anaesthesia while group B received additional ultrasound-guided erector spinae block given at thoracic level-T5 with 20ml of 0.25% bupivacaine. Time to first rescue analgesia was the primary outcome. Secondary outcomes were total intraoperative opioid consumption, pain scores over 24 h, post-operative nausea and vomiting and patient satisfaction score at discharge. The Shapiro-Wilk test was used to check the normality of each variable. A comparison was done using Mann-Whitney test and the level of significance was set at 0.05.

resultsThe median time to first rescue analgesia in group A versus group B was 1 h (1-12h) versus 8 h (1-26h), respectively, with a

conclusionUltrasound-guided ESP block with general anaesthesia offers superior post-operative analgesia compared to general anaesthesia alone in patients undergoing unilateral nonreconstructive breast cancer surgeries.
