Short-Term Cardiovascular Sequelae Following In-Office Posterior Nasal Nerve Cryoablation.
Article in Laryngoscope investigative otolaryngology, 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
Objective: Evaluate the post-procedural cardiovascular effects of posterior nasal nerve (PNN) cryoablation in comparison to inferior turbinate reduction (ITR). Methods: Patients over 18 years of age who underwent in-office PNN cryoablation or ITR via submucosal resection via radiofrequency ablation between 2019 and 2022 were enrolled. Cardiovascular parameters including systolic blood pressure (SBP), heart rate (HR), in addition to visual analog pain scale (VAS), were collected at baseline and perioperatively. Maximum changes and time to return to baseline were recorded. Results: A total of 25 patients were enrolled in the study (16 PNN, 9 ITR). The median maximum change in SBP in the PNN and ITR groups was significant at 36.5 mmHg (IQR 22,50) and 11 mmHg (IQR 0,17) respectively ( Conclusion: PNN cryoablation is associated with greater and prolonged effects on SBP in comparison to ITR when using a similar in-office anesthesia protocol. Surgeons offering this procedure should be aware of these effects when counseling patients and developing a protocol for post-procedure monitoring. Level of Evidence: 2.
