The effect of different dosage of intranasal dexmedetomidine on preventing emergence delirium or agitation in children: A network meta-analysis of randomized controlled trials.
Article in PloS one, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThe clinical evidence for the effects of different doses of intranasal dexmedetomidine on emergence delirium/ emergence agitation (ED/EA) in children is lacking.
methodsWe searched the PubMed, EMBASE and Cochrane Library from the establishment of the databases until December 30, 2023. All randomized controlled trials that evaluated the effect of different dosage of intranasl dexamedetomidine in children younger than 18 years on postoperative ED/ EA were included. Data analysis was conducted using R 4.3.0.
resultsA total of 15 randomized controlled trials involving 1566 children were included. Compared to 0.5 μg/kg (RR = 4.81, 95%CI = 1.66-13.94), and normal saline (RR = 8.23, 95%CI = 4.63-14.65), intranasal dexmedetomidine at doses of 2 μg/kg significantly reduced the incidence of ED/ EA in children. 2 μg/kg was the most effective dosage in reducing the incidence of ED/ EA (Probability of rank = 0.75), the incidence of severe ED/ EA (Probability of rank = 0.45), and ED/ EA score (Probability of rank = 0.65). Moreover, intranasal dexmedetomidine at doses of 2 μg/kg significantly reduced the PACU pain compared to 0.5 μg/kg (RR = 0.42, 95%CI = -0.22-1.06), 1 μg/kg (RR = 0.18, 95%CI = -0.26-0.63), 1.5 μg/kg (RR = 1.00, 95%CI = -0.54-0.75), and normal saline (RR = 8.23, 95%CI = 4.63-14.65), with a probability of rank = 0.45.
conclusion2μg/kg intranasal dexmedetomidine is the optimum dose for reducing the occurrence of ED/ EA and postoperative pain. However, further research is required to verify our findings.
