1 · What the graph read from 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.

2 · The registry

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

There has been exponential growth in the awareness and understanding of gastrointestinal (GI) dysfunction in Parkinson's disease (PD) over the past 3 decades. The clinical features of GI dysfunction in PD have been clearly identified and innovative research has demonstrated the presence of pathology within the enteric nervous system (ENS) in individuals with PD, leading to suggestions that the GI system may be ground zero for the genesis and the portal of entry of PD pathology, which then ascends via the vagus nerve to the central nervous system (CNS). This theory, as well as the more recent recognition of the association of PD with dysbiosis within the gut microbiota, has been the object of intense study and scrutiny. Since most PD medications are absorbed through the GI system, the need for better understanding of changes within the GI tract that may potentially affect the pattern of response to medications has become evident. In this review, current knowledge of the pathophysiology of changes within the GI tract and the gut microbiome of individuals with PD, including changes that occur with progression of the disease, will be addressed. We focus on common clinical GI problems in PD that can arise from different segments of the GI tract. Relevant diagnostic evaluations and treatment options for each of these problems will be reviewed.
