Changes in plasma arylsulfatase A level as a compensatory biomarker of early Parkinson's disease.
Article in Scientific reports, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Lysosomal dysfunction has been associated with Parkinson's disease (PD). However, the activity of lysosomal enzymes is heterogeneously observed in PD. We investigated whether arylsulfatase A (ARSA) level can be used as a fluid biomarker of PD and can reflect disease progression. Plasma ARSA level was measured in 55 patients with early and drug-naïve PD, 13 patients with late PD, and 14 healthy controls. We compared the plasma ARSA level among the groups and assessed its correlation to clinical parameters and striatal dopamine transporter (DAT) activity. Plasma ARSA level was not correlated with age. The early PD group had higher plasma ARSA level than the control and late PD groups. In a generalized additive model including all patients with PD, the plasma ARSA level showed an inverted U-shape according to disease duration, peaking at 2.19 years. In patients with early PD, plasma ARSA level was positively correlated to parkinsonian motor score and negatively to striatal DAT activity. In summary, plasma ARSA level was elevated in early stage of PD, and elevated plasma ARSA level was correlated to the clinical and imaging markers of nigrostriatal degeneration. These results suggest that ARSA level is a potential biomarker of compensation in early PD.
