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
purposeCongenital pulmonary airway malformation (CPAM) is a developmental lung malformation that seriously endangers children's health. The objective of this study was to investigate the etiology of CPAM by observing changes at the molecular and cellular levels.
methodsPatient clinical data were collected and analyzed. Tissue samples were collected from CPAM lesions and marginal normal lung tissue during CPAM surgery. The samples were subjected to hematoxylin and eosin (H&E) staining for pathological analysis. Tissue RNA was isolated for RNA sequencing, and the differentially expressed genes (DEGs) were enriched for Gene Ontology (GO) analysis. The cytoskeletal and cell subtypes were subjected to immunofluorescence staining.
resultsRNA sequencing of 7 CPAM patients revealed 1252 DEGs, with 1041 upregulated and 211 downregulated. GO analysis revealed that biological processes related to cilium organization and movement were strongly enriched. Protein-protein interaction (PPI) network analysis highlighted genes such as CCDC65, DNAH5, DNAH11, DNAH12, CFAP43, CFAP70, PIH1D3, RSPH4A and DNAH6 as potentially important in CPAM. Immunofluorescence staining revealed abnormalities in cytoskeleton and cilia, and a reduction in the number of alveolar epithelial type II (AEC II) cells in CPAM lesions compared with normal lung tissue.
conclusionOur study revealed a significant increase in cytoskeletal and cilia expression, along with a marked reduction in AEC II. These abnormalities provide potential insights into the etiology of CPAM and may guide the development of improved diagnostic and therapeutic strategies.
