Intraoperative Dexmedetomidine and Postoperative Delirium After Head and Neck Cancer Surgery with Free-Flap Reconstruction: A Secondary Analysis of a Randomized Placebo-Controlled 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
Background: Postoperative delirium is common after major head and neck cancer surgery. We investigated whether intraoperative dexmedetomidine infusion was associated with a lower incidence of postoperative delirium in patients undergoing head and neck cancer surgery requiring free-flap reconstruction. Methods: This was a delirium-focused secondary analysis of a single-centre, randomized, double-blind, placebo-controlled trial. Adult patients with head and neck cancer scheduled for elective surgery requiring free-flap reconstruction under general anaesthesia were randomly assigned to receive intraoperative dexmedetomidine infusion at 0.3 μg kg Results: There was less delirium during the initial 5 postoperative days in patients assigned to dexmedetomidine (14.9%, 7 of 47 patients) than in those given placebo (34.7%, 17 of 49 patients). Dexmedetomidine was associated with lower odds of postoperative delirium after adjustment for age, preoperative Mini-Mental State Examination score, and operative time (adjusted odds ratio 0.31, 95% confidence interval 0.10-0.92; Conclusion: In patients undergoing head and neck cancer surgery with free-flap reconstruction, intraoperative dexmedetomidine infusion was associated with a lower incidence of postoperative delirium during the first 5 postoperative days, without an apparent increase in perioperative adverse events.
