Remifentanil Diminishes Stimulation-Induced Oral Tissue Blood Flow Changes.
Article in Anesthesia progress, 2026. 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
Objective: This study aimed to investigate the effects of remifentanil infusion under inhaled anesthesia on changes in oral tissue blood flow and tissue oxygen tension during noxious stimulation of the oral region. Methods: Sixteen male Japan White rabbits were used. General anesthesia was maintained with sevoflurane or desflurane. Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean blood pressure (MAP), heart rate (HR), mandibular bone marrow tissue blood flow (BBF), masseter muscle tissue blood flow (MBF), mandibular bone marrow tissue oxygen tension (PbO2), and masseter muscle tissue oxygen tension (PmO2) were measured before and after electrical stimulation, with and without remifentanil. Results: Remifentanil decreased the rate of change in SBP, DBP, MAP, BBF, and MBF, whereas PbO2 and PmO2 remained unchanged. Conclusion: Remifentanil suppressed hemodynamics and oral tissue blood flow changes after electrical stimulation and maintained oral tissue oxygen tension.
