Comparison of the Efficacy of Intravenous Dexmedetomidine versus Intravenous Clonidine for Controlled Hypotension during Functional Endoscopic Sinus Surgery: A Prospective Observational Study.
Observational study in Annals of African medicine, 2025. 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
backgroundPeriprocedural hemorrhage is common during functional endoscopic sinus surgeries (FESSs) owing to the rich vascularity of the nose, which obscures the surgical field and increases the time of the procedure with complications. Controlled hypotension can be employed to mitigate the problem.
objectiveComparison of clonidine and dexmedetomidine as an infusion dose to effectuate controlled hypotension during sinus surgery. PATIENTS AND
methodsA prospective observational study was done between Group Dexmedetomidine and Clonidine who were posted for FESS with 40 participants per group. Both the groups received the allocated drugs in 100 ml of normal saline 15 min before induction. The patient's hemodynamics, Nasal bleeding, and surgeon's satisfaction score were noted.
resultsBoth Groups showed a drop in hemodynamics after induction, but a higher drop was seen in Group D. Nasal bleeding and Surgeon's satisfaction scores were better in Group D compared to Group C.
conclusionsControlled hypotension can be achieved with the preinduction infusion of either clonidine 3 μg/kg or dexmedetomidine 1 μg/kg. Dexmedetomidine provides better hemodynamic stability, decreased bleeding, and an excellent surgical field when compared to clonidine.
