Ketamine Sub-Dissociative Dose Vs. Morphine Sulfate for Acute Pain Control in Patients with Isolated Limb Injuries in the Emergency Department: A Randomized, Double-blind, Clinical Trial.

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
objectiveTo compare the ketamine efficacy at a sub-dissociative morphine dose to reduce pain in isolated limb traumatic injuries.
methodsA double-blind randomized clinical trial study was carried out on patients referred to emergency departments (EDs) due to isolated limb traumatic injuries. Eligible patients were divided into two groups which one group received 0.1 mg/kg ketamine and the other group received 0.05 mg/kg morphine, intravenously. An observed side effect includes pain scores and vital signs were recorded at baseline of every 5 minutes for 30 minutes.
resultsTotally, 73 patients with the mean age of 32.9±10.4 were enrolled of whom 59 (80.8%) individuals were men. The baseline characteristics difference of the two study groups was not statistically significant. The results showed that the change of mean pain score was -6.2 (95% CI: -5.72 to -6.69) points in the group receiving ketamine compared to -5.8 (95%CI: -5.15 to - 6.48) in the group who were administered morphine. At all assessed checkpoints, the pain mean score was lower in the ketamine group than in the morphine group (
conclusionThe study findings suggest that the sub-dissociative ketamine efficacy in controlling of the acute pain is not lower than morphine sulfate in patients with isolated limb trauma in ED's. Thus, it can be considered as a safe and effective alternative approach.
