Overview of the study design and analytical workflow. Endometrial tissue was collected from pre-receptive (PR), receptive (R), and post-receptive (PS) phases from healthy fertile controls (HC) and patients with recurrent implantation failure (RIF). Bioinformatic analysis included differential gene expression (DEG) and alternative splicing event (ASE) identification, immune cell estimation, RNA-binding protein (RBP) motif enrichment, and drug repurposing analysis.
