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

Decreased glucose tolerance is recognized as a factor associated with Parkinson's disease (PD) progression, yet the relationship between HbA1c and PD prognosis remains insufficiently explored. Using data from the Integrated Epidemiological Unit (IEU) open Genome-Wide Association Study (GWAS), PD's IEU-b-7 and HbA1c's IEU-b-104 were extracted. RNA-seq data from GSE20292 and single-cell RNA-seq data from GSE157783 were retrieved from Gene Expression Omnibus (GEO). Mendelian Randomization (MR) analysis, with HbA1c as the exposure and PD as the outcome, was performed using the inverse variance weighted (IVW) method. Differentially expressed genes (DEGs) between PD and controls in GSE20292 were identified, and overlapping instrumental variables (IVs) and DEGs pinpointed a set of candidate genes. Machine learning refinement selected biomarkers, leading to the development of a PD biomarker-based nomogram. Key cell lineages in GSE140231 were characterized, and communication and pseudotime analyses explored cell crosstalk and evolution. Using 223 independent single nucleotide polymorphisms (SNPs)as IVs, HbA1c was found causally [IVW: Odds Ratio (OR) = 1.438, P = 0.026, 95% Confidence Interval (CI) = 1.043-1.981].. Among 625 genes associated with these SNPs, 842 DEGs were identified by comparing PD vs. controls, intersecting with 27 candidate genes. Notably, five biomarkers-FASN, MICAL3, TCIRG1, CDK10, and MFSD1-emerged as potential diagnostic targets for PD. The receiver operating characteristic (ROC) curve demonstrated the high diagnostic accuracy of these biomarkers. Analysis of key cell lineages revealed strong interactions between excitatory and inhibitory cells and oligodendrocyte precursor cells and Astrocytes cells. In conclusion, HbA1c is identified as a risk factor for PD, with FASN, MICAL3, TCIRG1, CDK10, and MFSD1 representing promising targets for PD diagnosis and treatment.
