Improving lymphopoiesis in aged bone marrow.
Review in Current opinion in hematology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 of reviewAging is associated with impaired B lymphopoiesis and T lymphopoiesis, contributing to immunosenescence and poor immune recovery. Although this decline can be attributed to intrinsic hematopoietic stem cell aging, growing evidence indicates that lymphoid failure reflects constraints operating across multiple levels of the hematopoietic system. This review frames age-associated lymphopoiesis decline as a systems-level problem and outlines conceptual avenues for therapeutic intervention. RECENT
findingsAge-associated lymphoid failure is increasingly attributed to inflammatory suppression, dominance of dysfunctional stem and progenitor states, and compromised extramedullary support. These insights provide a framework for interventions that restore immune competence by rebalancing hematopoiesis or selectively replacing compromised stem cell function. SUMMARY: Age-associated lymphoid decline arises from coordinated constraints across the bone marrow niche, stem and progenitor composition, and extramedullary lymphoid support, rather than intrinsic stem cell exhaustion alone. Targeting these bottlenecks in a context-dependent manner offers multiple routes to improve lymphopoiesis and restore immune competence in aging.
