Comparative efficacy and safety of irreversible (rasagiline) and reversible (safinamide) monoamine oxidase inhibitors as add-on therapy for Parkinson's disease.
Synthesis in Journal of neurology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundParkinson's disease (PD) is a progressive, neurodegenerative condition caused by progressive loss of dopaminergic neurons of the substantia nigra. Safinamide and rasagiline are both novel medications that are indicated for PD. Safinamide (reversible) and rasagiline (Irreversible) are selective monoamine oxidase B inhibitors which work by decreasing the degradation of dopamine in the brain.
objectiveThis network meta-analysis aimed to examine the efficacy and safety of both drugs as add-on therapy in patients with Parkinson's disease. METHODOLOGY: A systematic literature search of PubMed, Embase, and Cochrane databases was conducted in September 2024. Primary outcomes were Changes in the Unified Parkinson's Disease Rating Scale (UPDRS-III) and adverse effects. Standardized mean difference (SMD) and odds ratio (OR) were calculated with 95% confidence intervals. Surface Under Cumulative Ranking Curve (SUCRA) was used to compare individual interventions. The Cochrane risk-of-bias tool for randomized trials (RoB 2) was used to assess the risk of bias in studies.
resultsThe search query resulted in 557 studies. After screening, 15 studies were included in the final analysis, totaling 5676 participants. Safinamide (100 mg) was associated with the highest change in UPDRS-III scores (SMD = 0.3007, 95% CI = [0.1710-0.4304], z-score = 4.54, p value = < 0.0001, I2 = 55.8%, SUCRA = 71.17%), with rasagiline (1 mg) being a close contender with a SUCRA of 70.64%. Safinamide (50 mg) had the lowest odds of serious adverse events (SAEs) with OR = 0.4394 (95% CI = [0.2231-0.8652], z-score = - 2.38, p value = 0.0174, I2 = 0%, SUCRA = 99.34%). Safinamide (100 mg) had the second-lowest odds of SAEs (OR = 0.9575, 95% CI = [0.6520-1.4061], z-score = - 0.22, p value = 0.8246, I2 = 0%, SUCRA = 66.96%). Almost all the studies had a low risk of bias.
conclusionSafinamide (100 mg) has good efficacy outcomes, whereas safinamide (50 mg) has favorable safety outcomes as compared to rasagiline for add-on therapy for PD.
