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
Introduction: Dysfunction of vascular endothelial cells (VECs) is a common feature of both psoriasis and diabetes. Comorbidity of these two conditions increases the risk of diabetic foot ulcer (DFU), yet the shared mechanisms remain unclear. Aim: This study aimed to systematically elucidate the shared pathological mechanisms of the two diseases from the perspective of VECs and explore their association with the pathogenesis of DFU. Material and methods: We integrated and analysed single-cell transcriptomic data from skin samples of healthy controls, psoriasis patients, diabetes patients, and DFU patients. VECs were clustered and annotated, followed by application of differential expression analysis, weighted gene co-expression network analysis, and protein-protein interaction network analysis. Results: VECs could be classified into five distinct subclusters. We identified 561 co-upregulated genes in VECs from both psoriasis and diabetes, and 12 core shared genes (e.g., CEBPB, ABL2) were further pinpointed, which were highly expressed in clusters A and P and showed upregulation under Conclusions: This study provides an explanation for the comorbidity mechanism of psoriasis and diabetes as well as the risk of vascular complications, laying a foundation for developing cross-disease therapeutic strategies targeting VECs.
