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

Ageing is associated with cognitive decline, which is a significant factor in the development of dementia. Vitamin B12 (VB12) is crucial for maintaining proper nervous system function, as well as for protein, fat, and carbohydrate metabolism, and DNA synthesis. Moreover, it helps prevent serious health conditions such as pernicious anemia, neurodegenerative diseases, and Alzheimer's disease. VB12 deficiency is common among the elderly population. We found that serum VB12 levels were significantly elevated in centenarians. Interestingly, VB12 supplementation delayed aging but also improved learning and memory in nematodes. Our results suggest that increasing VB12 activates ptp-3 and helps maintain good cognitive function in centenarians. Furthermore, aging is the gradual decline in bodily functions that impacts nearly all living organisms, with significant effects on salivary glands. Salivary gland degeneration may contribute to VB12 deficiency in the elderly, underscoring the crucial role of salivary regulation in VB12 absorption for centenarians.
