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

The common occurrence of cognitive decline is one of the most significant manifestations of aging in the brain, with the hippocampus - critical for learning and memory - being one of the first regions to exhibit functional deterioration. BGLAP/OCN/osteocalcin (bone gamma-carboxyglutamate protein), a pro-youth systemic factor produced by the bone, improves age-related cognitive decline by boosting hippocampal neuronal autophagy. However, the mechanism by which hippocampal neurons detect BGLAP/OCN in the systemic milieu and adapt their downstream response was previously unknown. We determined that BGLAP/OCN modulates core primary cilia (PC) proteins, suggesting that this "extracellular antenna" may play a role in mediating BGLAP/OCN's anti-aging effects. Furthermore, selective downregulation of core PC proteins in the hippocampus impairs learning and memory by reducing neuronal macroautophagy/autophagy. In contrast, restoring core PC protein levels in the hippocampus of aged mice improved this phenotype and was necessary for the induction of autophagy machinery by BGLAP/OCN. Together, these findings reveal a novel mechanism through which pro-youth systemic factors, like BGLAP/OCN, can regulate neuronal autophagy and foster cognitive resilience during aging.
