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

background and purposeParkinson's disease (PD) is a neurodegenerative disorder characterized by deposition of intraneural inclusion bodies in the brain as well as the enteric nervous system. Emerging concepts regarding the brain-gut axis have been proposed for neurological disorders. Thus, the present study investigated the associations between colectomy and developing PD.

methodsWe conducted a retrospective cohort study using National Health Insurance Service-National Sample Cohort of Korea. This study included patients who underwent colectomy during 2003-2009, and up to 10 individuals per patient, matched in terms of age and sex, who did not undergo colectomy. The colectomy group was subdivided by the causes and surgical methods of colectomy. The risk of PD occurrence was evaluated over a follow-up period of at least 6 years using Cox regression analyses.

resultsColectomy was associated with a higher risk of developing PD (adjusted hazard ratio [HR]: 1.962; 95% confidence interval [CI] 1.002-3.840). There was no significant difference in the occurrence of PD among the subgroups classified by the causes or surgical methods of colectomy.

conclusionsColectomy was associated with the development of PD, suggesting that colon issues play an important role in the pathophysiological mechanisms of PD.
