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

In this study, we noninvasively tested the hypothesis that Mn(2+)-enhanced magnetic resonance imaging (MEMRI) is sensitive to age-related changes in Ca(2+) influx occurring in the hippocampal region CA1. Uptake of Mn(2+), an MRI contrast agent and Ca(2+) surrogate with low cellular efflux rates (days to weeks), was measured in longitudinal MEMRI studies involving 2 separate groups of male Long-Evans rats: one group was studied at 2.5 and 7 months of age, whereas the other was studied at 7 and 19 months of age. Separate or combined analysis revealed that the extent of Mn(2+) accumulation in CA1 significantly increased with age (p < 0.05). These results provide first-time in vivo confirmation of the calcium hypothesis of aging and justify future longitudinal studies combining MEMRI with behavioral testing to investigate mechanisms of age-related cognitive decline.
