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 objective of this study was to evaluate the relationship of amyloid burden, as assessed by florbetapir F 18 ((18)F-AV-45) amyloid positron emission tomography, and cognition in healthy older control (HC) subjects. Seventy-eight HC subjects were assessed with a brief cognitive test battery and positron emission tomography (PET) imaging with (18)F-AV-45. A standard uptake value ratio was computed for mean data from 6 cortical regions using a whole cerebellum reference region. Scans were also visually rated as amyloid positive or amyloid negative by 3 readers. Higher standard uptake value ratio correlated with lower immediate memory (r = -0.33; p = 0.003) and delayed recall scores (r = -0.25; p = 0.027). Performance on immediate recall was also lower in the visually rated amyloid positive compared with amyloid negative HC (p = 0.04), with a similar trend observed in delayed recall (p = 0.06). These findings support the hypothesis that higher amyloid burden is associated with lower memory performance among clinically normal older subjects. Longitudinal follow-up is ongoing to determine whether (18)F-AV-45 may also predict subsequent cognitive decline.
