Prevalence of Rhinorrhea in Parkinson Disease: A Systematic Review and Meta-analysis.
Review in Neurology. Clinical practice, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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
Purpose of Review: To perform a systematic review and determine the prevalence of rhinorrhea in Parkinson disease (PD). Recent Findings: Of 451 patients with PD and 233 controls, the pooled prevalence of rhinorrhea in patients with PD was 45.0% (95% confidence interval 33.94-56.40), which was significantly greater than that in controls ( Summary: There is a high prevalence of rhinorrhea in patients with PD; therefore, providers should query for rhinorrhea during visits and understand the treatment options available. Future studies should explore the pathophysiology of rhinorrhea in PD and the relationship between rhinorrhea and disease severity and duration, as well as determine whether treatment-specific outcomes differ in patients with PD.
