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

backgroundDexmedetomidine has been used as an adjuvanty added to local anesthetics to prolong analgesia following peripheral nerve blockade. The aim of this meta-analysis was to investigate the effect and safety of dexmedetomidine added to ropivacaine in brachial plexus block (BPB).

methodsA search strategy was created to identify eligible randomized clinical trial (RCT) in PubMed, Embase, and The Cochrane Library (updated May, 2018). The methodologic quality for each included study was evaluated using the Cochrane Tool for Risk of Bias by 2 independent researchers.

resultsTwelve RCTs were included in the meta-analysis (n = 671). As an adjuvant to ropivacaine, dexmedetomidine significantly reduced the onset time of sensory (mean difference [MD], -3.86 minutes, 95% CI -5.45 to -2.27 minutes; I = 85%) and motor (MD, -5.21 minutes; 95% CI -7.48 to -2.94 minutes; I = 94%). In addition, it increased the blockade duration of sensory (MD, 228.70 minutes; 95% CI 187.87-269.52 minutes; I = 93%) and motor (MD, 191.70 minutes; 95% CI 152.48-230.91 minutes; I = 92%). Moreover, the combination prolonged the duration of analgesia (MD, 303.04 minutes; 95% CI 228.84-377.24 minutes; I = 86%). There was no difference of the incidence of bradycardia (risk difference [RD], 0.01, 95% CI -0.02 to 0.05, I = 45%; P = .45) and hypotension (RD, 0.01, 95% CI -0.01 to 0.03, I = 0%; P = .57) between 2 groups.

conclusionDexmedetomidine added to ropivacaine in BPB has a better analgesia effect (shorter onset time and longer duration) compared to ropivacaine alone. At the same time, there was no difference in the incidence of bradycardia and hypotension.
