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: Parkinson's disease (PD) is the second most common neurodegenerative disorder with cognitive impairment as a prime non-motor symptom. Biomarkers can assist in detecting cognitive impairment, which normally follows movement dysfunction, and also assist in the differentiation of PD patients with and without cognitive dysfunction, facilitating the early diagnosis and disease management while also allowing for timely therapeutic intervention. Summary: Here, we have reviewed the biomarkers of Parkinson's disease from different sources i.e., body fluids (CSF, blood, salivary, urine and tear) and tissues (gut and skin), along with the techniques used for the detection of these biomarkers. We further discuss the importance of biomarker validation and the significance of cohort studies in biomarker discoveries. Key Message: The chapter is aimed at updating the knowhow of the disease biomarkers that may assist differentiation of these overlapping entities.
