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

objectiveThe meta-analysis was conducted to assess the effectiveness and safety of intravenous administration of dexmedetomidine for cesarean section under general anesthesia, as well as neonatal outcomes. MATERIALS AND

methodsWe searched PubMed, Embase, Cochrane Central Register of Controlled Trials and the China National Knowledge Infrastructure database for relevant randomized controlled trials (RCTs) about the application of intravenous dexmedetomidine under general anesthesia for cesarean section. RevMan 5.3 was used to conduct the meta-analysis of the outcomes of interest.

resultsEight RCTs involved 376 participants were included in this study. The meta-analysis showed that the mean blood pressure at the time of intubation (weighted mean difference [WMD]: -15.67, 95% CI: -21.21, -10.13, P<0.00001), skin incision (WMD: -12.83, 95% CI -20.53, -5.14, P=0.001), and delivery (WMD: -11.65, 95% CI -17.18, -6.13, P<0.0001) in dexmedetomidine group were significantly lower than that in the control group. The heart rate (HR) at the time of intubation (WMD: -31.41, 95% CI -35.01, -27.81, P<0.00001), skin incision (WMD: -22.32, 95% CI -34.55, -10.10, P=0.0003), and delivery (WMD: -19.07, 95% CI -22.09, -16.04, P<0.00001) were also lower than that in control group. For neonatal parameters, no differences existed in umbilical blood gases at delivery, and Apgar scores at 1 minute (WMD: -0.12, 95% CI -0.37, 0.12, P=0.33) and 5 minutes (WMD: -0.17, 95% CI -0.13, 0.46, P=0.27) among two groups.

conclusionIntravenous administration of dexmedetomidine could efficiently attenuate the maternal cardiovascular response during cesarean section, without affecting Apgar score of the neonate.
