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

A 24-30 Centiloid (CL) threshold was collectively considered by a group of global dementia experts as a practical and implementable cut-off for anti-amyloid therapy intervention, in Alzheimer's disease patients who have been diagnosed at the mild cognitive impairment or mild dementia stage of their disease. Though additional validation is needed, knowledge of this threshold would be valuable to those involved in diagnosing and treating patients in the new AD care pathways, as well as entry into clinical trials. Therapy monitoring to determine future treatment response and assess amyloid clearance can be accomplished with amyloid PET with some technical details still to be elucidated.
