Risperidone-Induced Nasal Congestion and Increased Urinary Frequency.
Article in Cureus, 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
Risperidone is a second-generation antipsychotic that is widely used in the treatment of psychotic disorders. It is generally well tolerated, although uncommon adverse effects have been reported. Nasal congestion and urinary frequency have only rarely been described in association with risperidone treatment. A 27-year-old male with delusional disorder developed nasal congestion and urinary frequency after starting risperidone. He underwent evaluation by both family medicine and otolaryngology (ENT), and no alternative cause of his symptoms was identified. Despite treatment with antihistamines, intranasal budesonide, and xylometazoline, his symptoms persisted. The symptoms resolved when he stopped taking risperidone for two days and returned when the medication was restarted. Risperidone was subsequently discontinued and replaced with aripiprazole. Following the switch, the patient's symptoms resolved completely. This case suggests a probable association between risperidone and the development of nasal congestion and urinary frequency. Awareness of these uncommon adverse effects may help clinicians identify medication-related symptoms, avoid unnecessary investigations, and improve treatment adherence.
