1 · What the graph read from it

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.

2 · The registry

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

Osteoporosis and cognitive dysfunction, particularly Alzheimer's disease (AD), frequently co-occur in the elderly population, suggesting shared pathophysiological links. The emerging concept of the "osteoimmune-brain axis" provides a framework that emphasizes the immune system as the central mediator connecting skeletal and cerebral pathology. This review explores how the osteoimmune system-the dynamic interface between bone and immune interactions-influences brain function through pathways including systemic inflammation, cytokine release, and bone-derived hormones. We systematically synthesize evidence from basic mechanisms to clinical studies, with a critical appraisal of the strength and directionality of the evidence. Key questions addressed include: whether the observed associations are causal or merely associative; which bone-derived factors have human validation; and whether the axis primarily operates as a unidirectional driver, a bidirectional amplifier, or an epiphenomenon of shared aging processes. This review aims to provide a balanced theoretical foundation for future research and for developing prevention strategies targeting both skeletal and neurodegenerative diseases.
