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

Parkinson's disease is a progressive, widespread, neurodegenerative disease in which the involvement of the dopaminergic neurons of the substantia nigra results in significant dopamine depletion in the striatum. Newer imaging modalities reviewed here, using various radioligands, positron emission tomography, and single-photon emission computed tomography, have made it possible to assess the in vivo presynaptic and postsynaptic dopaminergic function. This is not only important from a diagnostic standpoint; these tests are being increasingly studied as surrogate markers to assess disease progression and responses to various interventions, including drugs. A brief comment on their role as a putative biomarker of the disease is also included. Because Parkinson's disease involves multiple neurotransmitter systems, neuroimaging of neurotransmitter systems other than dopamine is also discussed. Lastly, the evidence supporting the use of transcranial ultrasonography and substantia nigra hyperechogenicity in the diagnosis of Parkinson's disease is presented, along with some controversies that surround this technique.
