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

Neurodegenerative diseases (NDs) such as Alzheimer's and Parkinson's disease are characterized by complex genetic and regulatory landscapes. Genome-wide association studies (GWAS) and transcriptome-wide association studies (TWAS) have become two essential and complementary methods for investigating the genetic basis of these disorders. GWAS systematically identifies genetic variants associated with disease risk, while TWAS provides functional insight by integrating expression quantitative trait loci to infer the effects of genetically regulated gene expression on complex traits. The aim of this review was to provide a comprehensive overview of methodological developments and integrative applications of GWAS and TWAS in the context of NDs research. We first conducted a bibliometric analysis that delineates evolving research trends and identifies emerging focal areas in the field. We then compared the underlying assumptions, strengths, and analytical frameworks of GWAS and TWAS. Subsequently, we highlighted recent advances in TWAS methodology, including fine-mapping strategies, multi-tissue and single-cell modeling, integration of multi-omic data layers, and applications of machine learning and artificial intelligence. Finally, current challenges related to ancestry representation, reference panel diversity, and translational generalizability were also presented. By synthesizing these perspectives, this review clarified the methodological landscape, guided future integrative analyses, and supported the broader application of transcriptome-informed genetic approaches in understanding and treating NDs.
