Reproducible Molecular Subtypes in Systemic Lupus Erythematosus Are Associated With Disease Activity, Serology, and Distinct Trajectories Over Time.

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
objectiveSystemic lupus erythematosus (SLE) is biologically heterogeneous, motivating development of reproducible molecular subtypes that can track change over time. The aim of this study was to establish a reproducible molecular stratification of SLE across cohorts and platforms and connect the resulting subtypes to clinical activity, serology, and serum proteomics.
methodsWe computed Gene Set Variation Analysis scores for eight immune gene modules from baseline transcriptomes (ILLUMINATE whole-blood microarray [N = 1,756], LOTUS whole-blood RNA sequencing [RNA-seq; N = 585], and Genuity peripheral blood mononuclear cell (PBMC) RNA-seq [N = 812]). We clustered ILLUMINATE patients (K = 2-8) and selected K = 6, then used a random forest classifier to assign subtypes in LOTUS and Genuity. We analyzed serum proteomics (SomaScan in LOTUS; Olink in Genuity), assessed glucocorticoid associations with neutrophil modules, and quantified baseline to week 24 stability in LOTUS.
resultsSix molecular subtypes replicated across cohorts and corresponded to different levels of disease activity and serology (P < 0.001). Proteomic patterns converged with transcriptomics, with concordant differential proteins across Olink and SomaScan among shared targets. Neutrophils were a key axis: one neutrophil module tracked glucocorticoid use, whereas a second was glucocorticoid independent. In LOTUS, subtype assignments were mostly stable to week 24; when patients moved, transitions were nonrandom, occurred between adjacent subtypes, and were similar in the placebo group.
conclusionWe demonstrated reproducible SLE molecular subtypes (interferon, plasmablast/B cell, neutrophil) supported by independent proteomics. In LOTUS, subtypes were largely stable through week 24. When patients changed subtypes, transitions followed preferential trajectories, supporting longitudinal tracking and trial design utility.
