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

backgroundBasal cell carcinoma (BCC), the most common skin cancer, is driven by UV-induced DNA damage and shaped by immune surveillance. Although GWAS has identified over 140 risk loci, their cell-type-specific effects remain obscured by tissue-level averaging.

methodsWe integrated BCC GWAS summary statistics from a UK-based cohort (17,416 cases, 375,455 controls) with single-cell expression quantitative trait locus (sc-eQTL) data from 12 immune cell types in the OneK1K resource. Using the OTTERS framework combined with ACAT-O, we performed single-cell transcriptome-wide association analysis (scTWAS); bulk TWAS using GTEx whole blood served as a conventional tissue-averaged benchmark for comparison, rather than a definitive gold standard. Functional enrichment was conducted via Gene Ontology (GO).

resultsBulk TWAS using GTEx whole blood identified 35 BCC-associated genes (FDR < 0.05), including MC1R and CASP8. In contrast, single-cell transcriptome-wide association study (scTWAS) across 12 OneK1K cell types revealed 207 non-redundant susceptibility genes, predominantly in CD4ET, MONOC, and BIN. Functional enrichment uncovered cell-type-specific programs: MHC class II antigen presentation (CD4ET), PRR-mediated innate immunity (MONOC), and pro-inflammatory secretion (BIN)-all absent in bulk results.

conclusionOur exploratory scTWAS using healthy donor PBMC-derived eQTLs uncovered cell-type-specific BCC associations missed by bulk analyses, providing hypothesis-generating insights into immune-related genetic effects in BCC. This underscores how single-cell resolution can overcome signal dilution from cellular heterogeneity, though validation in tumor-derived immune populations is warranted.
