Role of prefrontal cortex in freezing of gait in Parkinson's disease: mechanisms and neuroimaging evidence.
Review in Frontiers in neurology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Freezing of gait (FOG) is a complex and highly disabling motor symptom that frequently affects patients with Parkinson's disease (PD), especially in the middle and late stages. Although traditionally associated with motor deficits, accumulating evidence suggests that FOG is also strongly influenced by non-motor domains, including cognitive dysfunction and emotional disturbances. The prefrontal cortex (PFC), a key hub for executive functions, attention, and emotional regulation, has been increasingly implicated in the pathophysiology of FOG. Structural and functional abnormalities in the PFC, particularly in the dorsolateral prefrontal cortex (DLPFC) and medial prefrontal cortex (MPFC), have been reported in PD patients with FOG. This narrative review aims to summarize current evidence on the role of the prefrontal cortex in the development and modulation of freezing episodes, focusing on neuroimaging findings. Clarifying the contribution of frontal lobe dysfunction to FOG may inform therapeutic strategies targeting frontostriatal circuits to improve mobility and quality of life in PD patients. This is a narrative review and does not employ formal systematic review methodology.
