Hypotensive anesthesia in maxillofacial surgeries: Current concepts.
Review in National journal of maxillofacial surgery. 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
Hypotensive anesthesia is a commonly used technique that aims to reduce intraoperative blood loss, consequently improving surgical field visibility and the need for blood transfusions post-operatively. It is widely used in major maxillofacial surgeries with a high risk of intraoperative bleeding. The aim is to reduce the patient's systolic blood pressure to 80 to 90 mm Hg and mean arterial pressure (MAP) by at least 30% of preoperative blood pressure or keeping a minimum MAP of 50-65 mmHg. Hypotensive anesthesia not only provides a bloodless surgical field but also helps to identify various anatomical structures. There are various pharmacological and non-pharmacological methods to induce hypotensive anesthesia. The decision to induce hypotensive anesthesia should be based according to the general condition of the patient, the extent of the surgery, and in coordination with the operating surgeon. The target blood pressure should be adjusted according to the patient's preoperative status and coexisting illness. The risk of organ hypoperfusion should be kept in mind. Close intraoperative monitoring with optimal patient selection is important for good patient outcomes.
