From correlation to causation: cell-type-specific gene regulatory networks in Alzheimer's disease.

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
introductionAlzheimer's disease (AD) involves complex regulatory disruptions across multiple brain cell types, yet the comprehensive intracellular causal mechanisms remain poorly understood.
methodsWe present an integrative analysis framework using single-nucleus transcriptomics with matched subject-level genotype data from 272 AD patients in the Religious Orders Study and Rush Memory and Aging Project (ROSMAP) and construct causality-based, cell-type-specific gene regulatory networks (GRNs).
resultsOur method identifies regulatory genes among transcription factors (TFs) and non-TFs, generating a complete and accurate causal regulatory map across brain cell types. Our analyses reveal both established and novel regulations, pathways, and cell-type-specific hub genes in AD. Beyond constructing transcriptome-wide GRNs, we quantitatively evaluate hub genes and distinguish those with regulatory versus responsive roles. DISCUSSION: Our study provides a comprehensive map of cell-type-specific causal GRNs in AD, with a methodology applicable to other complex diseases such as cancer, enabling dynamic pathway exploration, hypothesis generation, and functional interpretation. HIGHLIGHTS: Comprehensive causal regulatory maps across six brain cell types revealed cell-type-specific regulatory mechanisms that move beyond traditional correlation-based and TF-centric model limitations. Novel and established hub genes and functional modules were compared across cell types, providing insights into cellular functions related to AD. Hub gene roles as regulators or targets were quantitatively evaluated within cell-type GRNs. The constructed GRNs show upstream non-TF genes regulating TFs and interconnected TF regulatory modules, highlighting the complexity of AD regulatory mechanisms beyond TF-centric assumptions.
