The Effect of Intraoperative Dexmedetomidine Versus Morphine on Postoperative Morphine Requirements After Laparoscopic Bariatric Surgery.
Trial report in Obesity surgery, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05696886 (The Effect of Intraoperative Tramadol on Postoperative Opioid Requirements After Laparoscopic Sleeve Gastrectomy for Morbid Obese Patients), which is not on this map. Cited by 11 papers, 2 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.

Abstract
backgroundDexmedetomidine is an α
methodsSixty morbidly obese patients (BMI > 40 kg m
resultsThere was no significant difference in morphine consumption in the PACU (group D 12.2 ± 5.44 mg, group M 13.28 ± 6.64 mg, P = 0.54) or at 24 h (group D 40.67 ± 24.78 mg, group M 43.28 ± 27.79 mg, P = 0.75); when accounting for intraoperative morphine given group M had significantly higher morphine consumption when compared to group D (23.48 ± 6.22 mg vs. 12.22 ± 5.54 mg, respectively, P < 0.01). Group D patients had more cardiovascular stability.
conclusionsDexmedetomidine given prior to end of laparoscopic sleeve gastrectomy provides the same level of postoperative analgesia as morphine with better hemodynamic profile.
