Using endometrial immune profiling in young IVF patients: implantation rates improved for morphologically sub-optimal embryos.
Article in Frontiers in immunology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02262117 (A Prospective, Randomized, Controlled, Two-arm Study to Evaluate the Interest of the Pre-conceptional Endometrial Immune Profiling to Increase Birth Rates Through a Care Personalization in Reproductive Medicine Before IVF), which is not on this map.

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.

Abstract
Introduction: A balanced endometrial immune profile is considered to be the ideal environment for a successful implantation, as opposed to endometrial immune dysregulation. However, the embryo quality may be the pivotal 'immune' factor compared to the uterine immune environment. Study method: After providing informed consent, young infertile patients involved in ART underwent an analysis of their endometrial immune profile before their embryo transfer (ET). Each ET was classified as a Top transfer if the used embryos were of Top morphology; all other transfers were classified as non-Top. The live birth rate (LBR) after ET was compared between patients with a balanced endometrial immune profile and patients with a dysregulated endometrial immune profile, with no intervention to regulate the endometrial environment (conventional care). Results: Overall, the LBR did not differ significantly between patients with balanced and dysregulated endometrial profile receiving conventional care (39.5% vs 29.7%; OR: 1.55 [0.66-2.72]). However, among patients with a non-Top transfer, the LBR was higher in the balanced group (38.4% vs 21.2%; OR: 2.11 [1.02-4.37]). In contrast, no difference was observed in the case of a Top transfer (46.3% vs 45.8%; OR: 0.99 [0.38-2,55]). Conclusion: These preliminary results suggest that a balanced endometrial immune environment may favour the implantation in patients using morphologically suboptimal embryos. In contrast, an endometrial immune dysregulation negatively impacts the implantation of morphologically suboptimal embryos. Trial registration: NCT02262117.
