Effect of Controlled Hypotension on the Outcomes of Stapes Surgery.
Article in International archives of otorhinolaryngology, 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
Introduction: Stapes surgery (SS) benefits from adequate anesthetic bleeding control due to its microscopic nature and greater difficulty in hemostasis. Adequate hypotension during intervention is considered critical to achieving this goal. Objective: To evaluate the role of controlled hypotension (CH) on surgical outcomes in SS. Methods: We conducted a retrospective observational study in a tertiary academic center with adults submitted to SS from January 2017 to October 2022. Hypotension was considered controlled if the mean intraoperative arterial pressure was between 50 and 65 mmHg throughout the procedure. Patients were divided into CH and non-CH groups. Demographic data, medical history, anesthetic and surgical reports, perioperative complications, and audiometry results were studied. Results: A total of 99 SS procedures were included. Of those, 23 met the criteria for CH. The non-CH group presented a nonsignificant longer operative time (71.4 ± 21.3 versus 83 ± 27.4 minutes; Conclusion: Controlled hypotension in SS does not appear to impact the audiometric outcomes or complication rates, despite having a potential role in the surgery duration.
