Protective effect of dexmedetomidine infusion combined with epidural blockade on postoperative complications after surgery: A prospective randomized controlled clinical trial.
Trial report in The Journal of international medical research, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It has been retracted, and should not be counted. Cited by 12 papers, 7 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
objectivesThis prospective, randomized, controlled study aimed to explore the efficacy of dexmedetomidine combined with epidural blockade on postoperative recovery of elderly patients after radical resection for colorectal cancer.
methodsNinety-six elderly patients who underwent radical resection for colorectal cancer were randomly divided into the following four groups: dexmedetomidine, epidural blockade (ropivacaine), combined (dexmedetomidine + epidural blockade), and control (0.9% saline). The Mini-Mental State Examination (MMSE), Visual Analog Scale (VAS), and Ramsay scores at 48 hours, and time to first activity, length of hospital stay, and postoperative complication rates at 3 months were assessed.
resultsTwelve hours after surgery, Ramsay scores were higher in the combined compared with the control and epidural blockade groups. Twenty-four hours after surgery, MMSE scores were higher in the combined compared with the other groups. The combined group showed the lowest VAS scores except at 48 hours. Time to first activity and length of hospital stay were significantly shorter in the combined compared with the other groups. There was no difference in total postoperative complication rates among the groups.
conclusionsA combination of intraoperative dexmedetomidine infusion and epidural blockade could mitigate pain after surgery, improve cognitive dysfunction in early surgery, and facilitate recovery.
