Effectiveness of the Combination of Probiotic Supplementation on Motor Symptoms and Constipation in Parkinson's Disease.
Article in Cureus, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundParkinson's disease (PD) reflects the second most common neurodegenerative disorder and is associated with high morbidity and mortality. Besides the motor features, non-motor symptoms, such as constipation, are very common. There is accumulating evidence that neuroinflammation is associated with the PD pathological processes. Alterations of gut microbiota and microbial metabolites have been linked to the pathogenesis of PD. Previous research has shown that probiotic supplementation has beneficial effects on motor and non-motor symptoms and especially on constipation.
aimIn this study, we examine the effectiveness of a combination of probiotic supplementation (butyrate triglyceride 302.86 mg,
methodsThe present study is a retrospective study that examined the existing medical records of patients with diagnosed PD, having chronic constipation and used the probiotic supplementation for its management. A total of 41 existing medical records were screened. Medical records were excluded in the case of participation in another study for PD, suffering from irritable bowel syndrome, organic constipation, long-term laxative use changes in the standard dopaminergic treatment, Mini-Mental Status Examination (MMSE) score<24, hospitalization and antibiotic medication, and diarrheal syndrome. Nine medical records were excluded, and a final number of 32 medical records was finally examined. All 32 patients had evaluations carried out at baseline and three months after supplement administration. A stool diary questionnaire, the Unified Parkinson's Disease Rating Scale III (UPDRS III), and the Schwab and England and the Hoehn and Yahr scales were used for the evaluation.
resultsThe median defecation frequency was significantly improved. The supplementation administration significantly improved UPDRS III by 7.7% (from 35.72±15.51 to 32.97±15.71, p = 0.005) at month three, as compared to baseline. A positive effect was also seen in the Schwab and England scale. There was no effect on the Hoehn and Yahr scale.
conclusionThe enteric microbiome composition is altered in PD, and there is accumulating evidence that probiotic supplementation could alleviate disease symptoms in neuroinflammatory disorders.
