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

introductionMethods for standardizing positron emission tomography (PET) indices of β-amyloid (Aβ) (Centiloid [CL]) and tau (CenTauRz, CTRz) burden facilitates direct comparisons across radiotracers and supports in vivo biologic staging per the AT(N) (Aβ [A], tau [T], and neurodegeneration [N]) framework. In lieu of post mortem examination, visual interpretation is the most sensitive indicator of these pathologies. Here, we compared the performance of analytic and visual methods of AT(N) staging.

methodsA total of 149 participants were imaged using Pittsburgh Compound B ([

resultsCL quantification showed excellent agreement with visual Aβ staging, whereas T status derived from the CTRz pipeline was less sensitive to the heterogeneity of tau pathologic presentations indicated visually. Poor concordance was observed between visual and analytic N status. DISCUSSION: A combination of visual and analytic information is optimal for accurate biologic staging of AD. HIGHLIGHTS: The Centiloid method showed strong agreement with visual assessment for β-amyloid (Aβ) status. The CenTauR method was less sensitive than visual assessment for tau status. Heterogeneous tau deposition complicates tau standardization methods. Cortical thickness might not be the optimal index of neurodegeneration.
