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

purposeCardiac diffusion tensor imaging (cDTI) is signal-to-noise ratio (SNR)-limited due to diffusion signal attenuation, long echo times from gradient moment nulling, and moderate myocardial T

methodsSpin-echo cDTI protocols spanning nine voxel volumes were evaluated in healthy subjects (N = 11) at 3T. A gel phantom was scanned to compare SNR in a non-physiologic environment. Temporal SNR and regression fits were computed. Mean diffusivity (MD), fractional anisotropy (FA), bootstrapped uncertainties (

resultsPhantom SNR trends corresponded to theory, with consistent SNR increases. In vivo SNR increases differed between in-plane resolutions, in which

conclusionIn vivo differences in SNR slopes suggest a physiological bias-dominated environment. The
