Opicapone improves end-of-dose neuropsychiatric fluctuations in patients with Parkinson's disease.

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
Introduction: Non-motor fluctuations (NMF) represent one of the main complications that patients with Parkinson's disease (PD) may experience during long-term levodopa treatment. Opicapone (OPC), a COMT-inhibitor indicated for end-of-dose motor fluctuations (MF), has not been extensively investigated for the management of NMF. We evaluate the efficacy of OPC on end-of-dose neuropsychiatric fluctuations, the most frequent and severe NMF. Methods: We assessed 15 PD patients who underwent treatment with OPC (PD-OPC) compared to a control group of 15 PD patients (PD-CTRL). All patients had end-of-dose MF and NMF, confirmed by 19-item Wearing-Off Questionnaire (WOQ-19). For each, we identified the first end-of-dose deterioration period through MDS-UPDRS-III administered every 30 min over two consecutive days. On the third day, a comprehensive clinical and neuropsychological battery was administered during this designated period. Subsequently, OPC was prescribed to PD-OPC. After 6 months, patients were re-evaluated using the same baseline assessments during the same end-of-dose period. Results: At 6-month follow-up, PD-OPC showed significant improvement in the following tests: WOQ-19 ( Conclusion: OPC improved end-of-dose fluctuations in anxiety/depression, and executive functions/attention, while memory and visuospatial abilities showed little or no significant changes.
