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
Purpose: This study aims to construct a single-cell transcriptomic atlas of the developing rabbit sclera to elucidate fibroblast heterogeneity, differentiation trajectories, matrisome expression patterns, and intercellular communication, while revealing conserved molecular features of scleral cells through cross-species analysis. Methods: Single-cell RNA sequencing (scRNA-seq) was performed on scleral tissues from New Zealand rabbits at embryonic day 25 (E25) and postnatal days 7 (P7), 21 (P21), and 180 (P180). Libraries were prepared using the DNBelab C Series Kit and sequenced on the BGISEQ-2000 platform. Sequencing reads were aligned to the OryCun2.0 genome using STAR, and unique molecular identifier (UMI) count matrices were generated with PISA. Data preprocessing was conducted using Seurat. Fibroblast lineage differentiation was analyzed via VIA, intercellular communication via CellChat, matrisome expression patterns via AUCell, and cross-species analyses via CACIMAR and hdWGCNA. Results: We identified 7 major cell types and 15 subpopulations, with fibroblasts dominating the cellular landscape. Distinct fibroblast subtypes exhibited varied expression profiles and functions: KERAlow SPARCL1⁺ fibroblasts showed stem/progenitor-like features, while KERAhigh myocilin (MYOC)⁺ fibroblasts displayed senescence-associated phenotypes. Matrisome analysis revealed dynamic alterations in collagen and extracellular matrix (ECM)-related genes, and intercellular communication analysis highlighted complex signaling networks, particularly the MDK/PTN pathway. Cross-species comparisons demonstrated high conservation of fibroblasts between rabbit and human sclera, identifying four conserved co-expression modules. Conclusions: This study presents the first single-cell atlas of rabbit scleral development, unveiling fibroblast heterogeneity, ECM remodeling mechanisms, and cross-species conserved features. These findings enhance our understanding of scleral biology and provide valuable insights for future research on ocular development and associated diseases, including myopia.
