Ultrasound-guided pectoral nerve block for pain control after breast augmentation: a randomized clinical study.
Trial report in Brazilian journal of anesthesiology (Elsevier). The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers, 2 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.
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
objectivePectoral nNerve (PECS) block type-1 is an Ultrasound (US)-guided interfacial block that can be performed for postoperative analgesia management after breast surgery. In the procedure, a local anesthetic solution is injected into the interfacial area between the Pectoralis Major muscles (PMm) and Pectoralis minor muscles (Pmm). The present study compared PECS block type-1 administered preoperatively or postoperatively for postoperative analgesia after breast augmentation surgery.
methodsThe patients were randomly divided into three groups (n = 30 in each): a preoperative PECS block group (Pregroup), postoperative PECS block group (Postgroup), and control group (Group C). Opioid consumption and Visual Analogue Scale (VAS) scores were evaluated at postoperative period.
resultsThe pains scores in the Pregroup were significantly lower than those in the control group. Although there was no significantly difference in the VAS scores of the Postgroup and control group at postoperative 1 hour, the scores in the Postgroup were significantly lower than those in the control group at all the other evaluated times (p < 0.05). The VAS scores in the Pregroup were significantly lower than those in the Postgroup 8 hours after the surgery. Opioid consumption was significantly lower in the Pregroup as compared with that in the other two groups (p < 0.05). The use of rescue analgesia in the Pregroup was significantly lower than that in the other groups (p < 0.05).
conclusionPerforming PECS block type-1 preoperatively reduced VAS scores and opioid consumption after breast augmentation.
