LRRK2 p.G2385R and p.R1628P variants in a multi-ethnic Asian Parkinson's Cohort: epidemiology and clinical insights.
Article in NPJ Parkinson's disease, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
The frequency and clinical impact of LRRK2 p.G2385R and p.R1628P risk variants in Parkinson's disease (PD) remain uncertain, particularly across different Asian populations. We genotyped 3058 multi-ethnic Malaysian PD patients, performed detailed phenotyping in 185, and analyzed disease progression in 635 using longitudinal Clinical Impression of Severity Index for PD scores. p.G2385R was largely confined to Chinese (8.2%), while p.R1628P occurred in mixed ancestry (11.0%), Chinese (8.3%), Malays (7.7%), and is reported for the first time in indigenous groups (3.9%). Double-variant carriers had younger onset and more frequently had positive family history. Compared with non-carriers, p.R1628P carriers had lower rates of dementia and orthostatic hypotension, and slower progression of global PD severity. Our findings highlight ethnic differences in the distribution of LRRK2 Asian variants, and suggest that these variants influence onset age, familial occurrence, non-motor features, and disease course, with implications for personalized approaches to PD in Asian populations.
