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
This case report discusses a 62-year-old male with treatment-resistant bipolar II depression and hypertension. After poor responses to multiple treatments, an add-on esketamine nasal spray (ESK-NS) was introduced in October 2022. Improvement was seen, and the patient's depressive episode was nearly remitted during the maintenance phase. However, recurrence was noted when ESK-NS frequency was reduced to once every 2 months, indicating that the dosing frequency should be adjusted cautiously. The patient experienced common side effects, including dissociation, dizziness, and transient hypertension. Nifedipine was offered when his systolic blood pressure exceeded 160 mm Hg, accompanied by headache or dizziness. Blood pressure monitoring was essential throughout ESK-NS treatment. This report highlights esketamine's potential for bipolar depression treatment and calls for further studies on its cardiovascular effects and proper management.
