Efficacy of MAO-B and COMT inhibitors on quality of life in patients with Parkinson's disease: a Bayesian network meta-analysis.

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
Background and Objectives: Quality of life (QoL) is a critical outcome in the management of Parkinson's disease (PD), and is often affected more by non-motor symptoms (NMS) than motor features. While monoamine oxidase-B (MAO-B) and catechol-O-methyltransferase (COMT) inhibitors are commonly used with levodopa, their comparative impacts on QoL remains unclear. This study aimed to compare the effects of MAO-B and COMT inhibitors on global and domain-specific QoL in patients with PD using a Bayesian network meta-analysis (NMA). Methods: A comprehensive literature search was conducted using PubMed/Medline, Cochrane Library and Embase databases from the inception through April 30, 2025. Randomized controlled trials evaluating QoL using PDQ-39 or PDQ-8 in patients treated with MAO-B inhibitors (rasagiline, selegiline, safinamide) or COMT inhibitors (entacapone, opicapone, tolcapone) were included. A Bayesian NMA was performed using the " Results: Sixteen RCTs comprised of 3,802 patients were included. The combination of extended-release rasagiline and pramipexole (P2B001) showed the most significant improvement in global QoL (SMD = -4.16; 95% CrI: -7.24 to -1.05), followed by rasagiline monotherapy (SMD = -2.38; 95% CrI: -4.32 to -0.42). Safinamide 100 mg significantly improved emotional well-being (SMD = -2.56; 95% CrI: -5.13 to -0.04). SUCRA rankings confirmed the superior probability of benefits for rasagiline-based interventions across multiple QoL dimensions. Conclusion: This network meta-analysis provides evidence that MAO-B inhibitors, particularly rasagiline and safinamide, may offer broader QoL benefits in patients with PD, especially in NMS such as emotional well-being. These findings support a more symptom-oriented and individualized treatment approach should be provided to patients with PD. Further well-designed head-to-head studies using standardized QoL measures and extended follow-up are needed to confirm these findings and guide clinical practice.
