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

Neurofilament light chain protein (NfL) is a valuable biomarker for the differential diagnosis between Parkinson's disease (PD) and atypical parkinsonian disorders (APD). Here, we compared the performance of four cerebrospinal fluid (CSF) and three plasma NfL immunoassays in 253 PD and 265 APD. We measured NfL by ELISA in CSF and by SiMoA, CLEIA, and ELLA in both CSF and plasma. Additionally, we assessed Lewy body pathology by CSF α-synuclein real-time quaking-induced conversion assay (α-syn-RT-QuIC). In each biofluid, the tested assays showed comparable precision; however, CSF NfL showed higher diagnostic accuracy than plasma NfL for discriminating PD from APD (AUC range 0.966-0.974 vs 0.917-0.924). Combining CSF NfL and α-syn-RT-QuIC increased diagnostic accuracy. These results confirm the high diagnostic value of NfL in patients with parkinsonism, even when different assays are used. Combining CSF NfL and α-syn-RT-QuIC provides the highest accuracy, followed by CSF NfL and plasma NfL.
